It's designed for making and manipulating loops created on the fly from a live audio (or VST instrument) feed - eight simultaneous loops, which can all be mangled beyond recognition - and a built in automation system designed specifically for live use. The zip file contains stand-alone and VST versions, plus a pdf User Guide - and the software itself has its own built in help system to get you up and running quickly. Hope you enjoy it!

If you are a registered user of SM, the .osm is available on the Registered Users forum so that you can have a poke around inside... [old link]

Hahaha Cool i just love Trashing Beats....will get back to you soon,,, but thank you very much. Jamie 🙂

Just downloaded osm. Awsome stuff. Looking forward to seeing if my brain can understand it. Cheers

Hope you enjoy it - if you like it, keep an eye out for v1.2, I'll be upping it very soon. It should hopefully make the knob automation features easier to use, and I'm adding a bounce function (in the freeing-up-tracks-on-your-portastudio sense).

I am working on "bouncing" tracks, too...

It's been tough though...

I've been trying to use multiple banks of wave-read/wave-write primitives operating over a common buffer to make the copies faster than the samplerate.... and that's where I'm getting hung up.. it's a tough nut to crack.

8 wave reads at index offsets of 0 through 7 should facilitate an 8x samplerate copy... If I can get it to work I'll probably support maybe up to 64x copy speed.. even if it temporarily spikes the CPU a bit during the copy.

It's kind of funny that my main problem is that I haven't figured out a way to convince the thing to be able to start then STOP the copy operation... it always wants to be running, which is not what I want...

Part of the answer is in my last post on your looper code thread RE: shutting down unused loops. In short, the wave writes only run as long as they have an active output (and you can use a selector to turn them on and off). For your high speed copy operation (I wimped out and just did real-time!) - you can use a little trick with the Mono to Graph primitive. When triggered, this reads a precise number of samples into a float array, so that you can make wave displays etc. - but also it only registers as an active module while the reading is in progress. You can connect one of those to your wave write's outputs, and use it to enable the wave write for a specific number of samples. The only issue with this is that the Mono to Graph generates a float array - so you end up using a load of extra memory. You could maybe clear it though, by doing a quick one sample long write to a parking index. Alternatively, you'd have to use some sort of timer to turn the write's on and off using selectors - but you'll then need to find a way to compensate for the timing inaccuracy of the green logic needed to drive the selectors.

Now updated Soopa Doopa Loopa to version 1.2.0 (all downloads in the top post) The .pdf manual has also been updated with instruction for the latest features.

Registered users can have a peek inside the schematic HERE

As well as a few bugfixes and CPU optimisations, the update includes...

-Nastier Cruch effect -Simpler automation loop recording (just hold down SHIFT while knob wiggling) with fully independent loop lengths per parameter. -Main mixer controls now have Autofading feature. -Loop bouncing for copying loops or bouncing multiple loops to one loop slot. -Simpler headphone monitoring setup. -Customisable shortcut keys. -Expression pedal controller mapping. -Loop locking to prevent accidentally overwriting or deleting of loops.
