Hi All
I have recently been experimenting with patches that try to alter an LFO's rate without manually adjusting the pot. But since the AE'S LFO module does not have a dedicated CV input for this purpose, I have looked to other methods of producing the same effect. I have tried syncing the LFO's but this doesn't achieve the desired result, and I have also experimented with using a VCO's pulse signal in conjunction with a multimode divider to act as a variable LFO, where the divider triggers an envelope each time the pulse is reset and the VCO is then modulated by an LFO. This can in turn be used to modulate pitch and filter frequency but the results aren't smooth enough for my liking.
Another idea I had was to pitch two VCO's as close together as possible to produce a beat frequency and send both of these into the logic module, where the NAND output acts as the modulation source. But again even when the VCO's are synced together, the results are less than ideal. Can anyone tell me if they have had any success by using some sort of workaround?

You can modulate both the attack and decay of the 2env at the same time, that would work.

Gaëtan that's an interesting suggestion, thanks for that. Also do you think it might also be possible to physically modify the board of the LFO module to accept a CV input?

I don't know that, but if you don't mind the DIY route, head to the DIY forum section : I know that some members have built their own VCLFO modules.

Over on the Discord we actually had an interesting chat once about what the 2LFO module offers over the 2ENV module. And I think we came to the conclusion the 2ENV can do almost everything the 2LFO does + more. If you patch the envelope to be cycling, you can control the rate fairly easily. However, in my own experience I noticed that the attack & decay CV need a pretty strong signal in order to make a noticable difference, so it takes some tinkering to get the result you want.
However I suppose you cannot get a 'clean' triangle wave with the 2ENV as I think it does not have a perfectly linear response.
I might be forgetting something considering the 2LFO module and underestimating it, but I would be curious to hear what more experienced patchers think!

Yeah, I'm hoping for a VC LFO and a trigger delay.
