Any suggestions?

!PenButton1 alignWith: !KeyDown

To have this change the octave, you could multiply it by 12 half steps and add it to the pitch from the keyboard or tablet:

Anyway, a modified version of your suggestion worked for me:

!KeyPitch hz * (1 + (!PenButton1 alignWith: !KeyDown))

However, a problem arises in that I am using a polyphonic sound (preceding the Oscillator with a MidiVoice with polyphony set to 4). So now what happens is the sound changes the octave on the next !KeyDown, but you have to play four notes (going through the 4 notes of the polyphony) before the octave returns to normal.

How can I make this solution work polyphonically?

alignWith: is CapyTalk (not Smalltalk) and it is a relatively new addition (thus, it does not appear in the book). Update notes are available on the download page of the tweaky: http://www.symbolicsound.com/cgi-bin/bin/view/Know/KymaXDownloads

"However, a problem arises in that I am using a polyphonic sound"
I had assumed it was monophonic since you said you were triggering it from the tablet.

"How can I make this solution work polyphonically?"
You could add a check for the VoiceNumber if you know which voice you want to transpose:

!KeyPitch hz * (1 + (!PenButton1 alignWith: (!KeyDown * (?VoiceNumber eq: 1))))

I'm using a sustain pedal with the tablet. I suppose I could also be using multiple pens, if I had multiple pens. Hopefully, if I manage to come up with a sound that does some of these kinds of tricks I can post it to the Tweaky eventually.

Now I need a way to keep track of which VoiceNumber is current. Something that involves countTriggersMod?

penButtonoffsetpitchonnextKeyDown.kym

In the meantime, here is an example of how to do what you want. First, you use !PenButton2 to set !Offset. In the Frequency field, you don't actually sample the new value of !Offset until there is a !KeyDown:

!KeyPitch + (12 nn * (!KeyDown sampleAndHold: !Offset))

Next, you want to *reset* !Offset whenever the next !KeyDown occurs. But !KeyDown is local to each voice and you need a global variable to know when *any* key down has occured. Since continuous controllers are global to all voices, you can use a SoundToGlobalController in the MIDIVoice so that each local !KeyDown generates a global controller (called, in this case, !AnyKeyDown).

Outside the MIDIVoice, you can generate the !Offset controller such that !PenButton2 sets the !Offset to 1 and the *next* keydown (on *any* voice) will reset !Offset to 0:

!PenButton2 hasChangedReset: !AnyKeyDown

It also seems to mostly work as is, although there's some strange behavior. But take your time with the software update - I can wait.

[B]OK, it turns out there was a bug in CapyTalk that was interfering with alignWith (and a couple of other expressions as well). This has been fixed but will require that you download a new version of Kyma. We'll try to get one ready for everyone over the weekend.

I just found what I think is a bug, maybe one of the ones that you've also found, but wanted to check:

I've found that in polyphonic Keyboard setups, if I set the attack to a slow attack and then play more notes than I have polyphony, after I've played through the number of midi voices that I have, any notes that are then stolen are played with a short attack.

When Legato = 0, a re-attack immediately sets the envelope back to 0 and restarts the attack. However, when you have Legato = 1, the reattack begins from the *current* amplitude level, whatever that is.

If the envelope has not decayed all the way to zero and you reattack with a new pitch, that new pitch pops out at you as a sudden change. Oddly enough, if you put smoothing onto the !KeyPitch, you do not hear this as a sudden attack any more.

One solution would be to set Legato to 0. (This has the disadvantage of introducing a click when you voice steal and the envelope jumps to 0 immediately).
