Well, you did say no question is too silly...
I want to create a ramp up tempo change, i.e. start slow and build up to a faster tempo, then essentially maintain a constant tempo. I tried the naive approach (modulated the tempo parameter of the master clock), got into all sorts of weirdness, checked the documentation (in the Groove Clock section) and that says "You can also modulate the overall tempo by using parameter modulation on the tempo parameter of the master clock". So I am a bit flummoxed about the best way to do this.
The problem, of course, is that since I want a slow ramp, modulation sources like LFOs and the envelope are not appropriate (unless I'm missing something; always a possibility). Which leaves me the option of using the modulation sequencer. Unfortunately, the modulation sequencer (used in a naive way) is clocked by the master clock whose tempo it is modulating, so I end up with a completely uncontrolled rise in tempo. To be honest, I'm not entirely sure what it is doing, but given its behaviour it's clearly the wrong way to try and do this.
I've had some limited success stretching my basic knowledge of Numerology by adding another groove clock to control tempo for the bulk of the stack's step sequencers, with another modulation seq clocked to the master clock modulating that second groove clock's tempo. It kind of works, but since I want a ramp in, that modulation seq needs to be a one-shot and, as I've commented elsewhere, getting a reliable one-shot sequencer that doesn't kill the master transport is a bit beyond me at the moment.
So, has anyone else attempted this kind of tempo modulation? What's the best way to do this?
