So, knowing this is highly improbable, I'll still put it out there.
In the PCMSynth, when you open the Loop Editor, there is space for one more button.
It would look like a lock. It would allow you to Lock the loop points and then they (essentially the loop) could be swept forward or backwards thru the file. We can already sweep a static point in time, to a limited extent as I have shown, but not a loop .
So, if a sample were loaded, we could choose a loop length, let's say it was 4,096 samples. You could then, using automation, sweep the entire loop forwards or backwards.
Of course this would require extra work cause the algorithm would have to automatically smooth the loop to avoid clicks. I have no idea what that would entail and I'm not holding my breath.
The benefit? MASSIVE! Literally. This would put Caustic in the domain of NI Massive or, you know, Serum. Cutting edge shit.
On a side note I have zero idea what the legalities are of upgrades etc. but I'll throw this out there.
With any good DAW, upgrades are traditionally NOT free.
Perhaps a point in time will come in the future where it's worth considering adding a few features. Personally, I would GLADLY pay $9.99 or whatever for a Caustic 3.3 with the above feature and I doubt I'm alone, this type of wavetable manipulation is insanely popular right now.
It may not be even be possible but I can envision seeing Caustic 3.2 selling at $9.99, Caustic 3.3 selling at a higher price, and upgrading from 3.2 to 3.3 a different price as well.
There is probably 30 years of precedent in this approach but I'm not the one in the trenches. I can only make dumb and blind suggestions because I have no clue how GooglePlay functions or what the fine print said about any "rights" I have to free upgrades.
Just thought I'd throw it out there. Like I said, I'm not holding my breath and I still think Caustic, as is, is hands down the best audio software for Android by a mile.
