I want to make some chords out of my oscillators together. I want to feed 3 oscillators into the ae mixer and feed the mixer the output into a single filter. Is that OK to do? I don't want to overload the filter and cause a thermonuclear explosion.

Yeah, I've done that many times before. It's safe. The filter filters what ever frequencies you don't want in the final output, e.g., high, low, band, notch. The filter doesn't know what an oscillator(s) is. All it knows is there are frequencies coming in, and it's job is cut off undesired frequencies and resonate the frequencies at the cutoff if so desired. There's no overloading. It simply chops off whatever part of the sound you want. It doesn't care how many sounds are coming through.
One of the main tenets of West-coast synthesis is using multiple oscillators to create complex waveforms, then fold those waveform over themselves to create and even nastier waveforms, then you run that through a filter to smooth it out to whatever degree you prefer.
If you could overload a filter, then every noise module ever created would have blown out every filter ever created. Every earthquake or star ship sound you've heard in the movies is just noise run through a low pass filter.

Thanks funbun. It seems a logical thing to do, particularly as I want the same sound for each oscillator rather than using separate filters for each of them.

An attendum to your question is what mixer; if you don't need to adjust the amount of each oscillator output(s) the XMIX or B Mixer on the Mixer44 will do. I raise this though, because fading the different VCO output(s) in/out with the mixer can make some really cool sounds with or without a filter, and if you have CV control of the channel volume on the mixer (MIXCONSOLE module) this can be tied to key presses, envelope or LFO, whatever you want,  Endless fun.... |
