RE: [analogue-sequencer] Re: CV/gate quandary...

2010-07-18 by Sound Engineer

I'm another that votes for the D-type connector & breakout box combo but would also like to see included 1 or 2 pairs of CV/Gate outs (& 2 CV ins if possible, as mentioned) on the Cirklon itself, for those not needing the breakout option but just wanting to trigger an analogue monosynth or two. Appreciate this would put the cost up but think there would be plenty of users who would benefit from some on board CV/gate option.

As for the video i'm thinking that with Cirklon my DMX will soon be triggered the old skool way, even though it has the MIDI mod fitted...
Now i'm going to be looking to see if i can can mod an 808 for trigger inputs...
Whilst MIDI may have it's timing limitiations i'm sure all users will appreciate the wealth of MIDI outs to keep the formats latency to the very minimum at least.

Is there a pre-order avalaible for the Cirklon hey Colin, or deposit payments at least to secure a unit for the group users? 

Cheers,
Kev.

It was fortunate Ninestein didn't catch fire during the day, despite the

regulator heatsinks only being specced for the Scottish climate ;-)

I think I'm going to have to rebuild the 808/909 circuits in a bit less than

4U of full depth 19 inch rack.



The TRs 606, 808 and 909 all internally operate with 2ms timing resolution.

The point in time when they trigger their sounds will vary over a 2ms range

after the tempo tick.

But they trigger all the sounds to occur on the same beat at 'exactly' the

same time, within a range of a few microseconds.

MIDI can't put the start of each sound any closer together than two-thirds

of a millisecond.

IMO simultaneous triggering is very important for drum sounds, especially

electronic ones.

Multiple sounds on the same beat merge in different ways to form new sounds.

Triggering over MIDI, they always sound like a bunch of separate sounds

happening at roughly the same time.

The Cirklon CV output in mux mode is transmitting a sequence of 24 accent

voltages, and 24 trigger bits to the drum module, in a period of 1.6ms.

At the end of the refresh, all the triggers for that cycle are pulsed

simultaneously.
