I just released WOPR, a subtractive synth for iPad 2+ which eschews the usual LFOs in favour of a grid of evolving creatures called cellular automata. In practice that means you get complicated, tempo-synced rhythmic modulation of any synth parameter including signal flow & architecture.

WOPR is a powerful VA synth in its own right: stereo, 6 note polyphony, two oscillators with 4 wave types each, 32' to 1' range, +/- 500 cent detune, noise generator, twin assignable resonant LPF filters, twin delays (free and beat synced), three assignable envelopes, per-note pitch bending and a full-width keyboard. The modulation makes it into something else altogether.

Hi Scrumper, looks very promising, and I have invested my 69p... I particularly like the reference to Vintage 1970s code, being of that vintage myself ... But I have played with it for all of 30 seconds and one of the notes is hanging. I can't find a panic button anywhere, or any way of turning off that note! Can you help me?

Hi Richard,

Thanks for investing in WOPR. Sorry you've got stuck notes on there. You can tap the note again to stop it hanging. I've added a panic button to the current development version, so the next update you get after 1.1 will have this.

I spent a lot of time on the keyboard code to prevent stuck notes, but as everyone plays differently it could be that I've optimised it for my particular style. What were you playing at the time to stick a note?

Thanks

Hi and thanks Scrumper, for looking into it and putting a panic button on the next release. I've played with the synth a lot since I reported the problem and it has never stuck again, so it was a rare one off I think!

It's very different from any other synth I've got, for sure. Very good for random and beepy tones.

Good on you.

P.s. I'm sorry I can't remember what I did to produce the stuck note... Random messing around, I think I was playing several notes at once and sliding up and down the keys, because your synth does good slidey notes! Nothing as sophisticated as playing a tune, that's for sure!

Richard, great, thanks! WOPR puts a pretty hefty strain on the CPU when it's running all-out, so likely you got the stuck note while you were at the polyphony limit while still throwing new notes down and it just missed your 'note off' in all the confusion. If you're using the on-screen keyboard (rather than MIDI), this can happen when you have long release times on the envelopes. Again, stuck notes shouldn't ever happen, but I'm glad it's not occurred again. (I don't feel too bad about the odd random gremlin; my Korg Radias occasionally plays silly buggers and I think you could buy 700 WOPRs for the price of one of those...)

It's definitely got the sci-fi vibe about it. The patch "George and Gracie" shows that off nicely, if you use the pitch bending wribbon keyboard. Anyway, I'm glad you like that and I'm pleased you appreciate it for what it is.

If you have any other ideas or problems please feel free to use support@omnivoresoft.com or feedback@omnivoresoft.com. I can generally get back to people much quicker on that than on the various forums.
