Hello there … I see that my Behringer TD-3 can receive MIDI instructions for slide and accent, I was hoping to control these with the CV track on my A4 but the parameters are not available it seems, on the LFO anyway.
The TD-3 triggers a slide when the notes overlap in the sequence, the accent triggers simply with a note over 50% volume … I do not see these parameters on the LFO list … can anyone confirm they are not available for modulation on the A4? Any workarounds?
It seems normal that TD3 parameters aren’t available in A4 lfo destinations. 
A4 sequencer can send midi notes only.
Lfos don’t send midi. CV is not midi.
So what TD3’s manual says ? You need notes to overlap for a slide ? Doable with Note page LEN
Accent depends on velocity? Change Velocity in Note page.
just FYI - the velocity needed to trigger an accent is “more than 96” by default, not 63 (you can change it in the software app)
behringer did not really bother making anything CC controllable on the TD3, probably so they could keep it super cheap I guess.
or because it would be annoying the GODS OF ACID to make it work any way other than twiddling the cut off/resonance/envelope knobs.
(the first one I think)
Yep. Check TD3 MO version, which have much more midi or cv control.
Yes, I can make slides and accents, and it is much easier than the 303 type sequencer to edit and modulate on the A4, yes I can change note length or velocity but I can’t assign envelope or LFO to them. This was disappointing, I just wondered if I had missed something here …
ALSO I have successfully modulated the TD-3 filter from the A4 CV out, but it will only act as a filter at a fast mod rate … if the A4 CV is slower than a note (or something short) it ceases to act as a filter …
Hoping my Avalon arrives in time for Christmas … 
Unfortunately.
Ah it is surprising. I modulated a modded Monotron filter at different rates with lfo, or changed CV value with a knob, envelope…
The filter in jack on the TD-3 is for audio, not control voltage. Sending voltage offset will however do some changes to the audio, but its not filtering.
I looked int this, seems you may be correct … This is what I did … some kind of filter only control:
but this guy says it is affecting filter amplitude only:
He creates what he calls an FM effect, but surely that is AM…?
Its not really AM either. But when you insert cv into the filter input it will add a voltage offset to the oscillator. So it “pushes” the whole wave up/down. It will run out of headroom so it would disapear if the voltage is too high.
Something cool to do with this is using cv out of the TD-3 to control a couple of oscillators in a modular system. Run the audio from those back into the filter input. Then put the saw/square selector in the middle to turn off the internal osc. Then you have the “classic” 303 glide, accents and filter, but with what ever osc waveforms you want.
