Hello - This is my first post. I've been using Pd for a few years, but mostly on the GEM side of things. For about a month or so I've been tinkering with synths, reading and following along with tutorials, making notes, branching off into different ideas. I had the idea of a multi-oscillator additive synth, where several oscillator modules will be added to each other in sequence. The guts of each module are attached:
Here, two frequencies are summed, with the second frequency is the first one multiplied by a +/- 1 octave range. Lots of fun, especially with low frequencies. I've always been a knob-twiddler, so I have this (and a volume control above the dac~) set up to work with an ancient MIDI controller. However, I would like to be able to "sweep" the second frequency in "real time" while the summed frequencies are audible. I've been staring at this thing for a couple of hours now, and I can't seem to figure out where I need to go with this. Any pointers?
