200e

to add and subtract numbers of pulses,
make the 250e have a 'retreat' pulse input (as opposed to 'advance'),
by setting the stage addressing to strobed,
and patching a CV output to stage adressing CV input,
and setting the voltage output from each stage to address the stage before. the strobe pulse input then acts as a 'retreat' input.

then the current stage number is as an accumulator to which 'advance' pulses add and 'retreat' pulses subtract. have used this as a tempo difference meter comparing pulse frequency at 'advance' and 'retreat', and to synthesize signals at the tempo difference frequency.

many variations

also seems to suggest a few additions a sequencer might want......

had thought also of trying 256e in feedback around 266e sample and hold to do the adding and subtracting, but don't have the hardware at hand.

eardrill accumulator modulemodule? input_up, input_down, output...
eardrill wrap modulemodule? input, input_loThresh, input_hiThresh, output...

there seem to be a lot of "modular computer" ideas kicking around... my
prediction for the craze of 2011

oh my bad there already is one on the list!

hey chris, how are those modulemodules anyways?

The system is moving along nicely. I'm currently assembling modules from the first wave (blank, mults, atten, mixer, vca, and pulse balloons,) and getting the next wave ready for board layout.

The v.accum is in the second wave, along with the ADSR, and a couple more.

had an acoustic show to play tonight, and had the synth patched up already in the car, so we listened to it during setup to get in the mood. used the tempo difference meter to sorta PLL two pulse streams. the synthesized difference frequency CV speeding up one pulse stream and slowing down the other. many interesting rhythmic interactions and movements. was nice to see the meter swinging back and forth over 4 or 5 stages but not wandering off.

could narrow it down to just two stages, which I did for my bandmate who I remember used to like practicing drums by hitting every drum before repeating one, but not obviously. I wonder if he noticed

btw has the 250e firmware been revised to be able to put out a voltage corresponding to stage number? I heard something about that a while ago. that'd make it a bit quicker to set up with an offset of 15 (-1 modulo 16)

I realize now the stage address offset must function as a scale factor, multiplying the number of retreat pulses. perhaps useful for locking up a halftime etc pulse stream. will try tomorrow.

Yasi,

One can disable the voltage range for CV 1 and 2 (toggle until no LED 
indicator), which then gives you a voltage proportional to the stage number. If 
I'm not mistaken, it's not available from the Time CV though. I've also had some 
strange quirkiness occur when using this feature, but haven't been able to 
pinpoint it exactly.

Thanks for these patch ideas. Will make for some interesting experiments this 
weekend.

- Jason

oh a lovely surprise and loads of smiles to see you about here again yasi.  ;-]
