Hmm.. That rather sucks. Myself, I have been thinking about
creating a master 'timing brain' for the studio. A hardware box,
using which I can effectivly act as a conductor to sequenced music...
One more reason CV/Gate isn't really obsolete I guess.<br><br><div><span class="gmail_quote">On 10/31/05, <b class="gmail_sendername"><a href="mailto:WeAreAs1@aol.com">WeAreAs1@aol.com</a></b> <<a href="mailto:WeAreAs1@aol.com">

<br><br>Not impossible in the strictest sense of the word, but probably impossible in<br>a practical sense, which is what I think you mean. You're right about how it<br>might be done (sending clusters of clocks grouped close together, followed by
<br>"normal" clocks, followed by more clusters, etc.) Many MIDI devices may not<br>react so very well to this kind of schizophrenic data stream, even if it is in<br>fact "legal MIDI". It would be interesting, however, to try to implement
<br>such a thing with DIN Sync. DIN Sync would likely be a lot more forgiving about<br>an unsteady stream of clock pulses, at least on devices that use the clock<br>pulses to directly increment hardware counters.<br><br>
Even still, you certainly wouldn't have much resolution of variable swing<br>adjustment, because you'd still be dealing with the rather coarse resolution of<br>DIN Sync. I mean, a 16th note triplet takes up 4 DIN Sync (or MIDI sync, for
<br>that matter) clock pulses and a straight 16th takes up 6 DIN/MIDI pulses, so<br>you really don't have much room for variation in a 16th-based swing groove, such<br>as is found in much hip-hop music. 1/8th swing (typical "jazz" swing) would
<br>give you a little more wiggle room for swing variation, since 1/8th triplets<br>take up 8 clock pulses, and straight 1/8ths take up 12 pulses.<br><br>I'm still mulling over Mike Burnham's earlier question about getting swing
<br>out of a straight 1 pulse per note clock, such as we might use on a traditional<br>analog sequencer (his post was titled "shuffle cmos", a few days ago). I<br>think it may actually be possible (using a non-square pulse wave and some logic
<br>and timing stuff), but I haven't yet worked out the electronic details. Such a<br>system would have the advantage of almost infinitely variable swing amount --<br>it could even swing ahead or behind the beat (up to a point), and you could
<br>adjust the swing on the fly, just like you might adjust VCO Pulse Width on the<br>fly. In fact, you would need to use a clock that had variable pulse width --<br>probably some kind of sawtooth-based VCO with a variable pulse
<br>comparator/waveshaper, such as is found in most synth VCO's. But how to get two<br>positive-going pulses out of each cycle? That is, the first positive clock pulse happens<br>at the positive onset of the cycle, and the second positive clock pulse
<br>happening at the negative-going edge of the pulse cycle...?<br><br>Mike B.<br><br></blockquote></div><br>
