saveprevpitches.kym
 
I'm trying to save previous !Pitch to build an interactive sequencer. I think the script has no problem allocating memory for each pitches, but they don't seem to get pitch data.
Could you help me to do it?

Very cool idea (especially the part about testing whether the number of triggers equals the voice). I think the problem is that you have LoopFade set on the Samples that play back your saved !KeyPitches, and the fade in and out time is wiping out your 1 ms recordings.

It gave me an idea for an alternative way of buffering up events and regenerating them (see attached). This one uses a TriggeredSampleAndHold to latch the values and uses your same countTriggersMod: trick to know when to latch. I packaged the SoundToGlobalEvent right into the UserDefinedClass and made a little 5 note arpeggiator example with it to show a sample applications.

Eager to see your interactive sequencer when it's finished!

HI,

Your implementation has much less complexity and works stabler than mine, so I chose to use your idea. Now I can continue my project. I will share it when I finish it.

Thanks!

very nice idea indeed!
is there a possibility to combine the "buffered eventvalues" with the powers of the "analogSequencer" ?
i unsuccessfully tried to paste the included "latch a !KeyNumber in SampleAndHold" sound into the Pitches field of an analogSequencer.....

thx

Yes, it can use with AnalogSequencer. See "Interactive Sequencer" in the attachment.

Now I'm trying to measure the time between keydown and keyup so it can be used for duration field. I wrote some SmallTalk code and ran it, but it froze up the entire Kyma system! Can anybody have time to find out why? The sound is in "Don't Run." DO NOT run it. You'll lose any unsaved work.

Well, implementing duration might make "Interactive Sequencer" less useful though....

I've attached a small Sound that measures the duration a key is down in case it is useful in what you are trying to do.

(In your don't run example, you have an empty string as the Value. Could that be the source of the problem?)
