tap tempo conference Subject description: c'mon we can figure this out |
|

ok.
i've seen the tap tempo patches used to control a squarewave or the one in the help file for the zero-crossing counter.
i tried to make my own, to peg to the clock module. the problem i've run into is interesting.
the way i did it was to have a window switch running into a zero-crossing counter, and then sending the pitch out to a midi control send-which then controls the knob on the midi clock. novel approach, and one which got results EXCEPT that the range is all screwy, and some math/conversions need to be done. yet more maddening is the fact that it's not some simple addition/multiplication that needs to be done, but some kind of logarithmic scaling multiplication.
i think. after all, it needs to go from pitch to bpm. add to that the conundrum that i don't know what gets output from the zero-crossing counter-a midi number or a hz value!
anyone? please take pity. _________________ Astroid Power-Up!: "googleplex" available at:

I've been there , but I'm not satisfied.
As it's a "Conference" you started we want the full issue discussed here for future reference, right? Comments are welcomed....
Q: Why does one need TapTempo?
A: To sync to timed events OUTSIDE the G2.
(but strategies found could be applied to triggers derived from audio or MIDI clock divisions etc. )
Though my personal interest is synchronising delay times:
Things to sync to TapTempo:
Delay Time
LFO cycle
Sequencer Clock
Your additions to this list
Strategies encountered to generate a control value:
ZeroCnt generates a control signal after two taps.
Start a slow LFO saw on "Tap one", take a snapshot with a Sample and Hold on "Tap Two".
Your additions to this list
I've been trying Alby's BeatCounter ( http://www.electro-music.com/forum/topic-8367.html ) and it suffers heavilly of the scaling problems you adressed.
I have the feeling I could "almost" get the sequencer to be synchronised using Multipliers, Adders, Constants. But I've been at it for a couple of hours and tired of it.
Question: Has anyone tweaked this to satisfactory results?
The first tap restarts the sequencer, distracting me from focussing on the right tempo. I would prefer to start the sequence after the second tap.
Question: Does anyone know how to do this?
Question: Have you found what your're looking for?

Don't have a physical knob so have to do it with mouse clicks, for that I found it easier to make the switch a momemtary one. I can now just repeatedly hit it until the tempo is right and the beats are not really dusturbing then anymore but helpful rather.
Maybe that'll work for others as well ... _________________ Jan

I don't own a G2 myself, but I sort of had the impression you can't assign push buttons. Strange indeed.

Could you direct us to an example of a patch that has this in a workable condition? |

Not a better one than the one you linked to, that one works for the LFO it uses. For delays though there will be some more trickery needed and I never tried that.
Wild guess ... maybe use a Note/LevScaler to control the delay (between delay and ZzeroCnt output, set to L = 6 dB, R = -6 dB, experiment with BP) ? _________________ Jan

It's a pity that the clock modules do not have a rate input; therefore they can only be set to predefined bpm's, not to fractions or even to all individual bpm values (there are large steps at the tempo extremes). Of course, an LFO with some additional logic circuits can provide the same functionality; however, it is not as quick&easy (I know, I know, that's not what the G2 is about, but still).
For delay times, I have tried to make such a workable scaling, but recall to have noticed a weird relationship between knob-setting and delay times (but this was a long time ago). Therefore I used the 'sequencer-tables' in my tap-tempo patch, but this also suffers from quite severe stepping. |
