Have a look at this:

I was wondering about how you would go about doing something like this in Kyma?

Cheers

I'm guessing that the rich harmonic content of a piano note is ignored as the bulk of the piano notes frequency content is the fundamental so the extra harmonics are just left in without too much irritation to the sound.

So this could be done with an single analysis filter (from the prototypes) feeding an ABS (absolute) module which then feeds a peak detector which in turn is fed into the gate and velocity input of a sample player (with the piano note sample in it).

This would then put into a replicator module which controls the pitch of both the sample player and the filter (same note) to make all the iterations spread at semitone intervals.

Bob you could probably use a script instead of a replicator as I've seen some of your amazing script programing.

You will probably have to do attenuation to iterations as they goes up in pitch as pitch spacing will probably have too much HF energy.

You may need to make a few of these module clusters covering different ranges so that the sample player can have different samples for different notes ranges (to sound more piano like).

I noticed from the video that the lower keys were never used so you probably would not need to do all the notes.

hopefully the 1khz limit of the gate controls will not cause a problem, but if it does then you would have to replace the sample player with a wave shaper and the trigger would have to go through a low pass filter and in out characteristic module to form a linear ramp to feed it. This would give sample rate control. The gate would also feed a VCA to cut off the return to zero ramp and help with the velocity. This is where Pete's DSP modules would help but they don't work with the Paca(rana), and a Capy would probably not have enough power for the job.

I hope this makes sense.

Thanks for the replies.

I will have a play when I get some time and see what I come up with, if I have any success I will post it here.

Thanks
