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.

An 808 is easily modded, as is a 606 or 909. Purely digital machines may be
a little more complex.

The 808/606 have a pair of transistors on each instrument, to shift its
trigger pulse to the common accent level.
You can inject a variable voltage pulse of the right length via a diode just
after these transistors, and that will mix with the internal trigger so it
can still run from it's internal sequencer, but with full and independent
velocity control when triggering externally.
My 606 has a set of wires poking out the back, willing me to wire it up to
Cirklon.

Personally I think MIDI is the best solution for keyboard synths.
I share most of my MIDI busses between one mono- and one polyphonic synth.
With the monosynth on a lower numbered track, it gets timing priority, and
no more than 1ms delay.
That setup keeps me happy, and I am obsessively picky about timing.
With a local CV convertor or internal retrofit, I can send multiple 'CVs' to
a synth over one cable.

For synths like my Jupiter 8, MIDI is the only viable option.
CV/gate inputs would bypass the auto-tune, and that would be no use except
for jazz.
The JP has pretty poor internal latency anyway, more significant than the
MIDI delay.

If you're using soft-synths via USB, the USB port gives a 16x speed
improvement over serial MIDI.
I just need to enable a bit of code to move tracks assigned to USB outputs
forward in time to tune out the inevitable latency.
Not that I'd encourage anyone to use soft-synths.
But if you must... ;-)

There will be very soon.
I'll post here first when I'm going to put details on the web page.
Anyone who has mailed me in the past asking to pre-order/send money, etc.
will have a place kept in the queue if they wish.

A little Cirklon tune I just started is here, rollicking along...

Sweet, but hardly cleans the palette. Need the full meal now;^)

Sorry but it's morsels only (cue evil laughter) :) - here's another, 
just one scene this time with various tracks being unmuted and one synth 
being tweaked. It's not work-on much yet but I think I manage to use all 
16 tracks with chords on about three of them, just to see if it affects 
tightness. Let's just say that Cirklon's feeling so tight I may have to 
invest in some lube.

Another, just started today so forgive the wild scene changing that 
doesn't always come off. All I'm doing is selecting Cirklon scenes (like 
P3 parts but better) that I'll later order to become a song. Once I 
decide the order I like best that is.

It's no masterpiece, up there with Tracy Emin's bed though.
