random polyphony panning in stereo?

[_jojo_blue]

although I don’t know if this would be enough to create the piano effect, where all 88 keys would be spaced from the lowest notes to the highest from left to right

So thanks again! This is controlling the poly panorama with an LFO. And instead of an LFO, if I use volts of tones, I actually get a piano effect.

The two modules doing the heavy lifting in this example are Chinenual PolySort and Stoermelder SIPO:

From left to right, the first five modules are just a quick source of notes and gates.

Then the big contraption of tails/ms4/pmr modules is like a 16x version of tails.

The notes and gates that come out of this are interleaved (1,5,9,13, 2,6,10,14, 3,7,11,15, 4,8,12,16 ) so we need to use a custom sort order to match the sequential panning values that come out of SIPO

The Venom PolyOffset has the custom sort order which goes into the 1st and 3rd inputs of PolySort and the notes and gates coming out of each PMR go into the 2nd and 4th with the link button to sort them according to the preceding input before going into Palette.

The poly out from Palette goes into the L input on a Venom Mix 4 ST and will be spread according to the voltages fed into the Pan 1 CV input of the Pan expander. (Make sure to turn the attenuverter up.)

And finally, the part this whole example is all about: Using the same trigger from each note change for a sample and hold trigger as well as the SIPO trigger.

thanks for the next type, although quite complicated… can I ask why the sound cracks when changing tones?

[dustractor]

Hmm I didn’t have that issue. I’ll try some variations with other oscillator/vca combos and see if I can figure out.

When I inserted a short slew limiter between S&H and SIPO, it stopped popping.

For your first case of ‘pan with pitch like a piano’ here’s the trick

1. pitch is v/oct where middle c is 0, c an octave up is 1, c an octave down is -1
2. So you can use pitch as a control voltage to run a panner
3. If you do this then low notes (so v/oct is -2) would pan right and high notes (so v/oct is 2) would pan left

Here’s a simple patch that shows that made out of bog and vcv units.

The bacon music poly generator plays a bunch of polyphonic test signals. In this case it’s playing the third movement of the moonlight sonata which spans quite a bit of the keyboard. But since it only span about 5 octaves, i put the v/oct through a gain before I use it to make a pan to make the effect clearer.

hope that helps

Oh and to do the same with random placement replace the pitch source with an s&h.

here I had to use the menu to make bog S&H do +/- v rather than 0-10v but otherwise its all wired up on the screen

thank you very much for the answers, it’s already solved …
