Well, I 'might' like to see version # 1 first. I'm not sure how useful the huge steps like 9ths would be. Here are some thoughts from my side: On the cheap version, could the rotary step position sizes be user selectable / changeable? Say certain resistor sizes produce certain results? If they would be fixed then I think on the low side you MUST have 1/2 step (1 semitone). And, I think something smaller than 1/2 step would be cool to use for turning portamento into glissando -- kind of like you can gliss on the OB-8. On the expensive version, it would be MAJOR cool to have programmable scales. So, not just fixed step sizes for each step, but steps that would always be in key for the user selected scale. So the step might not always be the same. Hell, with CV out, I could finally actually play my theremin ON KEY with such a device. And, programmable scales would be absolutely killer for making oscillators track 3rd apart. Normally we use 5ths a lot as a musical interval because it is the same anywhere in the scale. However, the musical 3rd interval changes from 3 to 4 semitones depending on where you are playing in the scale. Sometimes it is a minor 3rd and sometimes major. One could use his keyboard CV to drive one oscillator and drive the quanitizer, and then use the quanitizer output to drive the second oscillator. Instant Emmerson like musical 3rd interval lead lines (except he could actually play them and always be in key). As the world turns / as the mind wanders..... This is a good thing.

I like! Version #3 Programmable tuning tables - up to 64 steps per octave for microtuning and gamelon scales (of course, you'd need to use an alternate controller since a keyboard's output is too coarse). OR, you could use say only 5 steps and program in a pentatonic scale, so that random large voltage swings IN = nice melodic scales OUT. Would be more expensive than the other two proposals cause you'd need a couple of buttons and a pot or encoder to program it.

You wouldn't really build something like that INTO this quantizer module - you'd use this quantizer module to add transposing to something else. For instance, set the quantizer to semitones, then patch a DC voltage to the input. COntrol the input level with an attenuator, and you have a stepped output that represents selectable intervals. Then just sum with your keyboard voltage at exactly 1V/Oct, and you have your quantizer acting as a transposer. You'd need a mixer or a summer with 2 precision 1V/Oct inputs.

(I was tired at 2am this morning, just wasn't thinking) Let's build a mixer into the module, then? I think a +/- offset would be nifty... I have a couple waldorf pulse patches which take inverted keyboard c/v and use it in various ways, it leads to some interesting patches. Andrew -| Andrew Schrock | aschrock@... |-

You only need 1 EPROM: the select switch controls the upper address lines. One 27C256 EPROM is big enough to hold 30 tables, easy. Let's do the math: Assume average table size is 1000 entries so 32768 address / 1000 = 32 tables. Yippee.

How about a footswitch input to go between 2 tables? But then, people would want to pick *which* two.... Maybe thumbwheel switches? I could silkscreen the table info in the panel, and you dial in which one you want (actually I prefer the ones with little pushbuttons) Or use 2 12-position rotary switches with a "fan" lettering (like Alesis and Lexicon use) to indicate the table.

I'd still like CV for dynamic reconfiguring, but for manual selection, the fan lettered rotaries are definitely the classiest and easiest to use, therefore most worthy of inclusion in MOTM. Dave

yes yes i'm waiting for it for so long. i would add a triger in/out jack's to allow the synchronization of the quantizing processes to other moduls like analog sequencer's... this is allso great when a LFO is patched in to the quant in put and then you quant only part of its rise/fall . allso a quantized transpose cv in jack ,i think its a must. Paul what is the process time of this unit would be,and what is the freq of it's intrnal clock ? and how about eastern scales ? thanx Gur Milstein At 22:58 29/09/99 -0500, you wrote:

Okay, so I'm admittedly somewhat modular-ignorant, & I'm not exactly sure what a quantizer does. Is it a way to make your 1v/oct keyboard play alternate scales or what? tomr
1999-09-30 by Paul Schreiber
It "forces" a CV in to be at certain levels, and not in-between. For example, if the quantizer is set for 0.0833Volts/step, that means a LFO input would sound like running your fingers over the keyboard.

But I could be interested in this initial installment in the quantizer line due to the price. I (very much) would like to see it implemented as a multi channel in multi, channel out -- so you could quantize a few different CV sources. I think that it would also be useful to have a resolution (between adjacent pitches) of 1/4 tone at the minimum end and maybe an octave at the high end (I can imagine using octaves much more than say sixths or sevenths). I also like the idea of being able to "move" through the tables via CV. It also seems that 1000 "notes" per table would be far more than necessary for most melodic quantizers, so maybe each EPROM could hold more than 30 tables. So I do hope that a more powerful quantizer would still be developed along the ideas that have been outlined by Dave (and the very quite Thomas) and me in previous posts. As it starts to approach DoMOAS, I still think that it might be worth trying to develop DoMOAS as a series of modules which interconnect rather than a Caddilac. JB

I think 1000 is a good number. I have messed with microtunings a fair amount and actually 1000 points maybe inadequate at times. I can actually think of much wilder things for the translation tables to do though and the more points the better here. Things like non-linear humps and valleys in the table--with an LFO driving it, it could get wild--especially when the LFO is going fast! Thinking more about it, why note make the traslation table variable as per each EPROM? This would allow lots of little tables or a few gigantic tables.... --Shemp

I don't get this. At 1000 pitches in a table, and assuming a ten octave range of hearing we see 1000/10 = 100 pitches per octave. How can this be too few except in the most theoretical case? This is well beyond my ability to discern pitch differences. Another way to say this: I've never needed a 1000 note keyboard.

I'm thinking that these ideas might be better implemented by VC lag processors, VC sample and holds, and VC waveshapers -- though I agree that a quantizer could be interesting in this instance. Probably missing the point again John (my perfect keyboard would have only one note -- the right one) Barlow

I don't remember if Encore's UEG has this feature or not, but if a simple ADSR or AR env gen had a knob to vary the A,D, and R times from log, to lin, to -log, that would be cool I think.. The 820 has this feature I belive, so the circutry is out there. Slap on one LED per stage so you could tune the slopes by eye and a loop/oneshot switch too. Second switch to either trig from a gate signal or a front panel pushbutton when in oneshot mode. seven knobs, two switches, three led's, one pushbutton, and four jacks. 2u. just a suggestion ~Steve M
