How difficult would it be / and would it even be worthwhile to have an alternate mode for Marbles where instead of taking an incoming steady clock and dividing/multiplying it, it would step forward on each pulse? Sort of like how the Wogglebug behaves. I know a mode like that would render the jitter ineffective and obviously the rate knob would not control the divisions/multiplications anymore but there have been many times where I would prefer to send it my own irregular pulses to step it forward instead of feeding it a steady clock. Do any of you who know more about this stuff than i do think this could be a feasible and/or useful mode for Marbles?
Some features of Marbles require the module to know in advance, at a given point in time, when the next pulse is going to happen (for example everything happening on the left side of the STEPS knob, JITTER, and clock multiplication).
However, if you don’t use these features, the module can deal with irregular pulses, both on the t and X clock inputs.
Interesting, thanks for the info. I will give it a try.
Hello folks, my first post so hopefully a relavent place for this.
I’m interested in modifying the Marbles firmware to allow for longer loop lengths.
What might be the theoretical maximum number of steps be?
Thank you @pichenettes.
I best start digging:)
Just change these two occurrences of 16:
to, say, 64 or 128. You’re adding more capacity for storing and replaying values.
And this is where the course of the DEJA VU knob is sliced into small 4° arcs to which a loop length is assigned. https://github.com/pichenettes/eurorack/blob/master/marbles/marbles.cc#L195
For example the value 5 is repeated 4 times, so it covers 16° in total of the course of the knob. I had to come up with this table empirically, because the response of the pot is not perfectly linear!
That is wonderful, thanks again.
I had an inkling about those two areas, can’t wait to try it out.
