I’ve been wanting a pedal I can turn on while playing music - primarily guitar but could be awesome for amplification of the more general audio experience… - which will oscillate the sound from left to right speaker.
In the long run I want to take this to the next level of a complete surround sound - front - rear - left - right sound system and be able to rotate the sound about myself at the center, will control over each speaker individually as well as pairs…
But lets start basic.
More or less, what I want is:
An on / off switch, ideally easily operable by foot which would engage the system when pressed and give true bypass to the sound when closed.
A dial to adjust the time taken for a full cycle of left speaker -> centered -> right speaker -> centered -> repeat ad infinitum…
A single input from big 6mm (?) audio jack, and two out puts, one for each speaker.
In theory I get vaguely what needs to happen, but by way of practical electronics to manifest this I think I’ll need a little help…
The bypass I could do… but the fancy bits to split the sound I don’t know how to translate electronically.
I’m visualizing effectively split of sound along varying percentages, with a dial to control rate of change, where the sound output is 100% left speaker - 0% right, 80% left speaker - 20% right, etc etc. in a cyclical manner.
Interesting idea. Do you plan to use this live? If so, will you gig with 2 or more guitar amps, or DI it into the PA? If the latter, pedal will need line level outputs, or a splitter to take stereo out plus a pass through to the rest of your effects. Otherwise, looks like 2 VCAs and a controller.
Now, put some delay on one of the channels and you might have something really cool.
Yeah, that’s the plan, already using delay and tremolo, and I think it’s a pretty powerful sound though tricky to record with my current means.
So the set up would be Tremolo and delay fed into the pan then to the speakers. I reckon 2 amps would be easiest? But the latter you mentioned perhaps more versitile?
Sounds like an LFO controlling the mix of the signal between two outputs, with a pot to control the rate. It might be useful to look at Leslie speaker emulations for inspiration, as they include rotation / directional output i think.
Ha, the latest evilution of the thought was a motor, axis of rotation in the vertical plane, with an arm with either LEDs or a sheild to block LEDs and light dependent resistors in a radial pattern from the centre linking to the output jacks.
Then just motor control.
Perhaps a dsp would be simpler… less interesting though…
