Cirklon CV ins/outs..

Cirklon CV ins/outs..

2010-09-01 by srmaietta

Hey Colin and list..
I asked on the Muffiwggler forum, which is the highest concentration of analog modular users anywhere and got a few opinions regarding what Cirklon should have, cv-wise..  I got some good thoughts and opinions, so here are the replies:

""I like the way the AUX outputs on the Kenton Pro-2000 are setup.. They can easily be configured to act as bipolar modulators, v/oct outputs, triggers, gates, etc. If something like that was possible - maybe with programmable slew - I'd be all for it... If we knew more about the proposed spec it would probably easier to make realistic suggestions. ""

""10 cv out, 10 gate out, 2 assignable ins, 1 clock in, 1 reset in."" (3 people voted for this)

""I'd like to see a few inputs as well. 
It would be great if it was possible to route the inputs to clock, reset, next pattern, previous pattern, pitch offset, or anything else that can be modulated with midi? 
So I say I'd like 8 inputs (if they can be configurable?), 8CV out and 8 gate out... 
But the best would be if there were 8 inputs that could be routed to any destination, and then 16 outputs that could have any source..""

""CV (software control of whether it is v/oct, hz/oct), gate and trigger (adjustable peak voltage and duration), a dedicated clock out (divisions selectable in software) would be nice, as would a clock in and a reset for when the sequencer is stopped. I agree with miminashi that having them configurable in software would be the best option (though perhaps not the easiest?). What kind of resolution would the DACs have? Being able to connect to the ground would be good for people that have banana systems, no? ""

As far as I remember a conversation with Collin the CV Outputs are quantized, so let's not expect kind of LFOs or similar.

at this point I think we need more information from Colin about what 
kinds of voltages could actually be output and input and especially how 
the inputs could be used within the cirklon

I'd vote for that, too.
But also for having, as additional option, a breakout box [also DIY is 
fine] with more outs, half CV half gates [and some CVins too].

Obviously with the CV capability still not finalised, the software support
is not final either.
The outputs will have 12 or 16 bit resolution, a range of 10 volts, and an
update rate across all channels of at least 1000Hz.
Logically, the CV outputs appear as if they were on a MIDI to CV convertor
built into Cirklon.
So far they can be assigned to output note, velocity or CC values.
The extra resolution of the DACs is used to provide linear or exponential
smoothing (i.e. glide).
In multiplex mode, I have it set to output a stream of 24 pairs of accent
and trigger signals, based on a drum map.
I've pretty much used it exclusively for drum triggering. That's what it
does best. Or, most best :-)
I'll have my real 909 on eBay before long. I just can't see me using it
again.

I don't have to be strict about the use of MIDI protocol internally, so if I
feel it would be worth providing higher-resolution step values for CV
output, I could.
But I find it pretty damn hard to pick out more than 128 discrete positions
on a knob, so its more important to me that transistions between values can
be smooth.
That is something that can be easily achieved by allowing a pattern to
switch smoothing of CC values between steps on and off as part of the
pattern, and using the extra DAC resolution to make the slope zipper-free.
Only the length row of a P3+ pattern has higher than MIDI resolution as yet.
There is scope to make the aux rows 12- or 16-bit if desired.

For CV inputs, there would be a conversion to a logical MIDI stream.
If it were converted to a note, velocity or CC value routed to the realtime
record input, it could be used to capture sequences from external devices.
Routed to internal track control parameters, it might modulate
note/velocity/length/delay offset or scaling, pattern settings like
direction and tbase, or the equivalent of P3 play-mode knob input for aux
events (so allowing control over masking of events, depth of randomisation,
etc.)

All this is flexible.
Just as with P3, I expect the final implementation to be strongly influenced
by user input other than mine.
It will launch with a very capable OS, but it would be foolish to try to
make it 'finished'.
There is plenty of scope for fun ;-)
The Cirklon CPU out-runs a P3 by about two orders of magnitude, and the code
space is only a third full.

Well that's exactly what I hoped you would say Colin - notes, CC/CVs 
triggers and gates flowing in either direction between analogue and 
digital - control over direction, time-base, masking and randomisation 
etc etc. Anyone with a modular synth should be peeing their pants 
reading that, basically. This all goes way, way, way beyond anything the 
P3 was capable of.

Cirklon could sit at the absolute centre of a studio controlling voltage 
controlled analogue, drum machines, midi synths and softsynths all at 
the same time and, crucially, have them all interacting with each other!

that is just awesome Colin

Hi all,

 

I'm new here! ;-) I'd say maybe something like the following would be sweet:

 

5 CV out

5 gate out

3 clock out with selectable division

3 start out

3 stop/reset out

 

1 CV in

1 gate in

1 clock in

1 start in

1 assignable in

Since we are talking features on the CV side, one thing that would be great
to implement on the CV outs would be LFOs that were free running, tempo
synced, or re-triggerable by a note event.
