Re: 272e frequencies in Japan and Russia?

the fm tuner chip advertises "Worldwide FM band support (76–108 MHz)": https://www.silabs.com/audio-and-radio/fm-radios/si4702-03-radio-receivers and in the source code these compile-time constants are set and used throughout: #define MIN_FREQ 8750 #define MAX_FREQ 10790 so it should be possible to ...

Re: WARNING for serge seller on reverb.

Not good. Was this deposit back when they were being made or recently? Story is that that friend split with the money or something along those lines.... back when the 259 was happening It’s my understanding from Dean that the person whom he trusted to help him assemble the 259s years ago started se...

yes, except instead of just mixing raw sinewaves the 400/700 use chebyshev polynomials so things sound more interesting.

I find that drawing the waveform manually is usually disappointing. I wonder how the waveshape editor works on the 700. the waveshaping on the 700 (and 400, touche, 259e, and probably other places i've forgotten) is based on drawing a transfer function for a sine wave (rather than drawing an actual...

No problem, I’m sure it’ll be great when you’re ready!
it's funny - i thought the dsp part would be the hardest but that was done a long time ago. dealing with cross-platform interface issues, weirdness in logic, vst2 vs vst3, auv3, etc takes way more time. who knew?

Obviously you won’t have all the analog vcf’s and vca’s but do you plan on having these in software to recreate the full feature set? sure - there's a filter on each voice and there was an attempt made at adding a bit of crunch to emulate analog vcas. I hope it will work on older ipads and not just...

That looks great. What control options are there for the various parameters - midi, OSC? so this gets complicated. short answer - the global controllers at the bottom of the screen are automatable by whatever host you run the plugin inside of. this is analogous to the 700's controller which only pr...

you might check with joel: http://www.isproductions.com/joel/

the rings usually just need a new battery. joel may also have a line on lightning wands (which can be used instead of the rings and use regular aa batteries).

totally a design flaw. when i found out i tried to compensate in software, that's why the 250e/222e/223e don't quite go up to 10v. i couldn't do the same trick on the 225e though because the cpu was already overtaxed and couldn't handle the math. the oscillators track pretty well when using the inte...

Mostly because B&A and BEMI give no access to the internal bus. What IMHO is a good policy to maintain things working. Some guys could think the oposite but....
