You should be able to edit this to your heart's content to create slow/fast sweeps. When you're ready I can create some polyphonic performances to test things properly.

Unfortunately there is a problem (I had to go out so have only just had time to try it). The audio file is fine, but the MIDI one is only 51 bytes long. Which is probably not much more than the header

Seemingly no longer an 'elderly'.
Now a 'Senior'. Is that promotion?

Odd. I'll fix it...

No idea what I did with that! I've re-done it from scratch. Try the above link again and hopefully it's sorted.

Thanks that one works.
Unfortunately it shows some step behaviour (which I was afraid of). This is almost certainly due to the fact there is no interpolation and the incoming values aren't regular 1,2,3 ...

Presumably, any incoming 7-bit data like CC's, aftertouch etc, need to be mapped to a modulation value and should always be interpolated and smoothed. How do you do this for other 7-bit MIDI data?

Any receiving device can only work with what it's being given, and I'm not sure how smoothly my controller is working, but yep, I guess some smoothing lag may be necessary.

Varies. Things like volume and panning it's a simple fairly coarse time-based operation. For frequency components it's still time based, but broken down into sample based corrections and has a faster effective response to small variations.

It's actually a good test track. If it had been too even I might have missed the problem, so thanks for taking the trouble to do it.
