All plug-ins updated for macOS 12 Monterey

The macOS versions of all Expert Sleepers plug-ins (AU, VST and AAX) have been updated for compatibility with the recently-released macOS 12 "Monterey".

Download from the downloads page.

Apple M1/Big Sur compatibility

All current Expert Sleepers plug-ins are supported and working on macOS 11 Big Sur, natively on Intel macs and under Rosetta on M1 macs.

We have started on native M1 builds. However the main limiting factor here is the lack of availability of a version of the PACE (iLok) tools with support for M1 builds. We anticipate that by the time the PACE tools are available, we will be ready with the native M1 plug-ins and will be able to release updates fairly swiftly.

All plug-ins updated for Logic 10.5 compatibility

The AU versions of all Expert Sleepers plug-ins have been updated for compatibility with the recently-released Logic 10.5.

Augustus Loop v2.2.1 (AU) released

Augustus Loop v2.2.1 is released. This is a bugfix release addressing some issues with the previous version (v2.2.0). As before, this is a 32/64 bit Intel only release for OS X 10.5 and above, so you only need this update if you specifically need the 64 bit functionality.

Issues addressed in this release:
- Fixed compatibility with OS X 10.5.
- Worked around a bug in Digital Performer 7.1 which would cause a crash when the plug-in prefs dialog was used.
- Generally improved stability of the Cocoa UI.

Download now from the downloads page.

Augustus Loop v2.2.0 released - 64 bit AU

We’re proud to announce the release of Augustus Loop v2.2.0.

This is a milestone for Expert Sleepers as it’s our first 64 bit release. Specifically it’s a 32/64 bit Intel Audio Unit, and so can be used in native 64 bit mode in Logic 9 and Mainstage 2.1 when those hosts are running as 64 bit applications.

From now on we anticipate that all our Mac releases will be Intel only, will support 64 bit use, and will require Mac OS X 10.5 or 10.6.

There are no new features in Augustus Loop v2.2.0 other than the availability of a 64 bit variant. If you’re not using 64 bit hosts, there’s no reason to take this update.

If you are though, download the update now from the downloads page.

Update: there appears to be a problem with this version’s GUI and Digital Performer. Please use v2.1.2 with Digital Performer (which is 32 bit, so there’s no reason to use this 64 bit build anyway).

Update: MOTU have confirmed this problem in DP 7.1.

Update: there is also a problem with this version and OS X 10.5. A fix is being worked on.

Analogue Bundle available

In addition to the previously mentioned bundles, the ‘Analogue Bundle’ is now available from the store.

The Analogue Bundle combines the analogue synth controller Silent Way with two analogue-sounding delays, Augustus Loop and Little Spacey.

The bundle is priced at $90, saving $37 on the price of the plug-ins bought separately.

A summary of all the currently available bundles and pricing is here.

Augustus Loop is updated to v2.1.1.

This version adds the new OSC functionality as recently added to Warbler and Silent Way for TouchOSC compatibility.

Rolled AL: another Augustus Loop script

Stephen Band has posted an Augustus Loop script in the spirit of the original multilooper example script and Axel's recent post.

Read about and download it here.

Extensive Augustus Loop/FCB1010 looping tutorial published

Axel Baesler, the author of the aforementioned script for Augustus Loop, has published his tutorial on how he's set up his (almost) dream looping environment. Read it here. Extract:

Ever since I figured out how to remote control clip recording in Ableton Live 7 over midi, which was about a year ago, I’ve been trying to build the “ultimate computer based loop station”. I’ve built increasingly more complex Live Sets utilized all sorts of routing tricks and midi conversion scripts and always ended up sort of discontent, because my setups could not be operated effectively with just the 10 switches and two pedals my Behringer FCB1010 midi controller provided. No matter what I tried, I always seemed to end up staring confusedly at the floor board wondering where the hell I was while my potentially brilliant musical idea vanished into thin air.

Then I stumbled over Expert Sleepers Augustus Loop 2 which provided a completely programmable midi control environment and I knew this would give me all I needed to come up with a controlling setup I could use to actually control my loops. The main remaining problem now was that if I used more than one loop the FCB1010 out of the box wouldn’t give me any feedback on what loop I was operating on. Then I found out about the unofficial Uno firmware upgrade ( I had a friend burn the downloaded image file on an eeprom chip and was now able to operate the unit in “stompbox mode”. In short, this makes it possible to have one row of buttons on the FCB1010 act as pedals that operate independently of the selected patches in the other row. Now, I can select a loop to control by stepping on one of the buttons in the lower row and the LED on this button stays on even when I press buttons in the upper row to manipulate the loop.

I have written my own lua midi script and gui for Augustus which I’ve been able to extend even further since Os, its ever helpful developer, has built in some event timing support. So, for the first time since I discovered the joys of live looping I’m very content with my setup. That’s why I’m making it public here. Maybe someone finds it useful, too. And hopefully I’ll get to making more actual music now instead of working on my setup (well, one can dream).

Augustus Loop v2.1.0 released + new script/skin

Augustus Loop v2.1.0 is now released (all formats/platforms).

v2.1.0 adds some new functionality to Augustus's MIDI/OSC and GUI scripting.

Timing functions

In MIDI/OSC scripts you can now
* get the time between two events
* ask for a function to be called after a certain amount of time, or regularly at a specified interval.

Using these functions you can do useful things like distinguish between short and long footpedal presses, or detect double taps etc.

GUI indicators for MIDI/OSC script status

A new form of the existing 'indicator' GUI item has been added, together with some corresponding MIDI/OSC script functions, to allow you to create GUI elements that reflect the state of scripted variables.

As usual, get the update from the downloads page.

These new features were developed after a request from Axel Baesler, who has used them to make a fairly complex script based on my Multilooper script. He's also made a custom GUI to go with the script, and provided a sample Live set and even a FCB1010 footcontroller patch to use with it. Get the script from the scripts page.

Augustus Loop v2.0.4 (AU) released

Augustus Loop v2.0.4 is now released. This is an AU-only bug fix release. It addresses an issue where no audio would reach the fx loop outputs with certain combinations of parameter settings.

Augustus Loop v2.0.3 (AU) released

Augustus Loop v2.0.3 is now released. This is another AU-only release, which further improves the behaviour of parameter automation in Logic - specifically:
* the pitch buttons now cause automation to be recorded.
* the four delay time parameters (delay slider min/max, max delay and delay time) now use 'high resolution' mode automation.

Augustus Loop v2.0.2 (AU) released

Augustus Loop v2.0.2 is now released. This is an AU-only bug fix release. It addresses an issue with recording parameter automation in Logic Pro.

Augustus Loop rated 'Excellent' by

Augustus Loop v2 has been awarded the "EXCELLENT" software certificate by

Augustus's page on that site is here.

So that's nice.

Augustus Loop v2.0.1 released

Augustus Loop v2.0.1 is now available (for all platforms) from the downloads page.

Changes in this version:
* It is now possible to completely override the default MIDI/OSC script with a custom script. (Previously it was only possible to extend the functionality, not replace it.)
* Added a new preferences option, 'Ignore AudioUnitReset', which can be useful when using the AU version of the plug-in in a live context. See the manual for a fuller explanation.

Augustus Loop v2 now released - skinning competition extended

Augustus Loop v2 is now officially released, and available for purchase.

Read the what's new page here, and download it from the downloads page. Remember you'll need a new licence manager too.

With regard to the skinning competition - in retrospect it wasn't reasonable to ask people to make skins using the beta release, so I'm extending the submission deadline until November 24th. Get going on those skins!

Some notes on the skinning competition

Some people have mailed me with questions about the skinning competition, so I thought I'd put all the answers up here, in case anyone else has a wonderingment about it.
  • I expect people to send me fully constructed skin bundles (like the examples). However I'm willing to accept just a pair of images that replace the images from the default skin, which can be combined with the default gui.lua script.
  • The maximum size of the GUI is 1024x512 pixels.
  • The background image doesn't have to be a small tile, as it is in the default GUI. It can be a single image that spans the entire GUI. Remember though that you need to round up your image to the next power of 2 size (e.g. if your GUI is 400x250 pixels, a background image would need to be 512x256 pixels).

Augustus Loop v2.0.0 beta (Windows VST) released

The Windows VST version of Augustus Loop v2 is now available - see the post below for more general details on the beta.

You can download the Windows version (and an updated manual) here:

Augustus Loop Skinning Competition!

We have three free licences (or upgrades) for Augustus Loop v2 to give away, and all you have to do to have a chance of winning is submit a new skin. Skins will be judged on aesthetic merit and/or interesting new functionality.

Email your entries using the Contact Us link below.

Closing date for entries is Monday 27th October 2008. Judge's decision is final. No cash alternatives.

Augustus Loop v2.0.0 beta (OS X) released

We're proud to announce a public beta release of Augustus Loop v2, a major update to our popular tape echo/looping plug-in. Only the Mac OS X (AU and VST) versions are available right now - the Windows VST version will follow soon.

For new features in v2, see the what's new page.

You can download the beta here:

You can also download example skins and scripts for use with v2.

Please note that Augustus Loop v2 uses a new serial number from previous versions, so if you have a licence for v1.8 or earlier it won't work with v2, and the plug-in will operate in demo mode. It is not yet possible to purchase licences for v2.

Please post comments and feedback on the forum.

Augustus Loop v2 approaching completion

Something of a milestone today - feature development work on Augustus Loop v2 is done, at least for the AU version. So all that remains is to make some presets, write the documentation (itself a not inconsiderable task) and then enter the world of hurt that is the VST and in particular Windows versions.
Stay tuned for a probably public beta of AL2 sometime soon.

OSC coming to Expert Sleepers plug-ins

In case anyone's interested (and I know at least one person is): starting with Augustus Loop v2.0, Expert Sleepers plug-ins will support OSC.

Open Sound Control (OSC) is a protocol for communication among computers, sound synthesizers, and other multimedia devices that is optimized for modern networking technology. Bringing the benefits of modern networking technology to the world of electronic musical instruments, OSC's advantages include interoperability, accuracy, flexibility, and enhanced organization and documentation.

The plan is to roll this out to the entire plug-in range eventually. If you need OSC in your favourite plug-in sooner rather than later, let us know!

I'd like to acknowledge Ross Bencina for making available the open source library oscpack, which has made it much easier than it could've been to get OSC up and running in Augustus Loop. Thanks Ross!

Augustus Loop planning

After much thought, I've decided that, despite the beta that was available a while back, the next version of Augustus Loop will not be v1.9.0 after all, but v2.0.0. So, apologies to those who were getting excited about the v1.9 features, but I think you'll be even more pleased with v2.0, which will have a whole load more new features in it, in part focusing on removing any possibility of clicks and pops from bad loops or sudden changes (e.g. when using Clear Loop).

One new feature that I'm very excited about is a whole new implementation of the Freeze Loop function, which IMHO has never quite lived up to expectations. I have that working already and it's awesome. Really.

I'll also use this message to announce that I'll be putting the price up a bit, mainly because v2.0 is a major upgrade, but also because of the continued weakness of the dollar against the pound (my prices are fixed in $ but I live in the UK so I receive the money in £). However my current plan is to continue my policy of making the upgrade price simply the same as the difference in prices of the two versions, so nobody buying the plug-in shortly before the new version is released will lose out. To put it another way - don't wait for the new version! Buy it now! Now!

Augustus Loop v1.9 beta expired

The Augustus Loop v1.9.0 beta 1 expired today. There will probably be another beta soon. In the meantime, please use the latest v1.8 version from the downloads page.

Augustus Loop v1.8.1 (AU) released

This is a small bug-fix release, aimed mainly at users of Logic Pro. Changes:
  • Fixed a problem where Augustus Loop's GUI would stop Logic's Key Commands from working.
  • Fixed an issue which could cause Apple’s AU validation tool (as used by Logic) to run very slowly when validating Augustus Loop on OS X Leopard.

Augustus Loop v1.9.0 beta 1 released (AU only)

We're proud to announce a public beta of a new Augustus Loop release. This is quite a big one. Changes:
  • Augustus Loop’s GUI is now fully skinnable and scriptable.
  • MIDI behaviour is now scriptable.
  • Added Record Offset feature, which helps with latency problems in live situations (see this thread).
  • Fixed an issue which could cause Apple’s AU validation tool (as used by Logic) to run very slowly when validating Augustus Loop on OS X Leopard.
You can download the beta here:
Please post comments and feedback on the forum.

Augustus Loop v1.8.0 released

Changes in version 1.8.0:

* New 6-in 6-out configuration of the plug-in, allowing audio to be routed through external processing either side of the virtual tape.
* Fixed an issue that could cause a crash in Logic 8 when opening a song containing multiple instances of Augustus Loop with their GUIs open.

Augustus Loop v1.7.3 released (Windows only)

v1.7.3 now works on systems which do not have SSE2, notably certain Athlon processors (SSE is still required). Systems with SSE2 continue to use an optimised version.

Augustus Loop v1.7.2 released (OS X only)

v1.7.2 fixes an issue which would cause the VST version to crash if the AU version were not also installed. It also further improves the plug-in's resilience to font installation issues.

Augustus Loop v1.7.1 released (OS X only)

v1.7.1 is a minor bugfix update, addressing an issue on certain systems which have had the system fonts moved or uninstalled.

See also this page.

Augustus Loop v1.7.0 released - Windows/OS X VST & AU

We are proud to announce the release of Augustus Loop v1.7.0. Changes for this release:
  • First Windows version.
  • First Mac OS X VST version.
  • New GUI.
  • Fixed various filter problems. In particular, the filter cutoff was being limited to about 2kHz - now the full range up to 8kHz is usable. Therefore, this version may sound different to previous versions at the same settings. A preferences setting is provided to revert to the previous behaviour, which may be useful if you have to re-visit an old mix after upgrading.
  • Added ‘Tape Stop’ feature.
This is a free update for owners of the previous version. Download from the downloads page.

Augustus Loop v1.7.0 beta 2 (Mac VST) released

The first ever Mac VST version of Augustus Loop is now available for beta testing. Features are the same as the earlier 1.7.0b1 (AU).

You can download it here.

Augustus Loop v1.7.0 beta 1 (AU) released

I've just posted the first beta of the new Augustus Loop. The main new thing is the new GUI, which has been re-implemented using the same technology as the other plug-ins. This is what's going to enable a Mac VST and Windows VST version of Augustus not too far in the future.

Other changes:
- The filter has been fixed. Previously the cutoff frequency was limited to about 2kHz, even though the knob goes up to 8kHz. Also it was possible to get nasty artefacts when using extreme filter LFO settings. Note: this does change the sound of the plug-in, if you were using cutoff frequencies above 2kHz. A global preferences setting to retain the old behaviour has been provided for people who need to use the new version to go back and revisit an old mix.
- A 'Tape Stop' button has been added. This is great for 'finger on the turntable' type effects.

Right now I'm very keen to hear from people who are experienced with previous versions of the plug-in, to find out if the new GUI has introduced any major issues.

You can download it here.

Augustus Loop v1.6.0 released

v1.6.0 adds 'digital mode', giving the option of clean, 'digital' looping, and saving CPU load into the bargain. See the manual for more information.

Augustus Loop v1.6.3 released

v1.6.3 adds 'rounded tempo' mode (a workaround for MIDI sync issues in Ableton Live).

Augustus Loop v1.6.5 released

v1.6.5 now responds properly to AudioUnitReset(), so in e.g. Logic the delay buffer will be cleared when song playback is started etc.
