FreqBox?

can you make the FreqBox self oscillate like the LowPass Filter?

it >is< an oscillator.

I'm still having trouble wraping my head around this, I'll just have to go down to the music store and play with it.

check the video. is quite helpfull.
its ok> it IS an unbelievable cool device!

I am really dying to have one.

Would you be able to use with a kenton Pro-solo to play it like a synth? (Is it 1V/Octave ?)

The only reaoson I am getting this is to be able to have a cheap version of a Moog synth when I put together the Freqbox with the rest of the foogers.

When self-oscillating, the LPF starts feeding back on itself, acting like a sinewave oscillator (but it was not designed with this in mind). The FreqBox IS an oscillator, the incoming audio controls/interferes/modulates the pitch of the oscillator creating distorted waveforms. It is similar to self oscillating the Moog LPF and then plugging an audio signal into the Frequency jack (CV input) on the back of the pedal. The audio signal begins distorting the sinewave. This method is exponential modulation of the waveform, where the FreqBox allows exponential AND linear modulation. Linear FM does not create the sound of VCO pitch bend (like exponential modulation does) making it more "musically useful." Finally, the FreqBox creates more complex waveforms than a self-oscillating LPF, so the distortion effect is more severe.
Hope this helps.

Jeez....... I have a pair on order from Big City. I want to try them out.

Sorry, this is likely a less than intelligent question, butall my readings on synths seem to skip the stuff I want to know...

When they're "hard sync'ing" the osscilatoer to the audio, how does this work with chords and droned notes (bassist)? If I hold a note and play a few others on the next string, should this thing follow all of them, or just one? It was said somewhere on here that it isn't tracking anything, so does that mean that the usuall limits on tracking on bass shouldn't be an issue?Also, for output, as its an oscilator sync'd to an audio signal, what can we expect for an envelope? Does the env. amount control use the original notes envelope to recreate the original dynamics on the oscilated signal?

I think I had a few more questions, but can't remember them right now... thanks for tolerating m lack of understanding!

i think the vco takes the average frequency with cords and such. but you can add harmonics with the fm amount. thats not exactly the same, but ok. you're "supposed" to mix the audio with the vco.
the simultaniously played high and low keys will give or the average key, or the vco will sync on strongest signal. i dont really know.

the envelope is exactly the envelope you put in, but only when you turn up the envelope amount offcourse.

somebody could correct me on this. cause i've not played with it yet.
