Re: [PLAN_B_analog_blog] Model 30 Frequency Shifting. There may be a way.....

2008-04-23 by tomas everaert

Maybe this would only work if the FM inputs were linear? Or am I wrong 
about this?
Another idea: maybe if you modulate the *level* of the slow oscillator 
with an external signal, would this not bring that signal into the 
model 30? If the level input is linear (is it?) then I'd guess the 
oscillator would output the external signal, albeit with an unavoidable 
tremolo determined by the rate of the slow oscillator. Or am I talking 
nonsense here?

By the way, maybe I should introduce myself to the community, this is 
only my second post to this list :-)
I am new to the modular synth world (although I have been looking from 
a distance for some time now) and have just started configuring my 
first Eurorack system, which should consist mostly of Plan B and 
Livewire modules. Just recently, I ordered the first ones: two Livewire 
AFG's.

(Although, according to it's subject, tis post should be about the 
model 30, I would like to mention that among the newly announced Plan B 
modules I was particularly happy to see the model 32. Since I want to 
be able to use my---still unexistant---modular as a standalone 
instrument with no need for external controllers, a joystick module is 
pretty essential for me. My first thought was Dieter Doepfer's joystick 
together with his manual gate, but now that I have seen the model 32 on 
photo, this is no longer an option: I want the model 32! :-) At last, a 
joystick module that has everything I think should be standard: a 
manual gate, external inputs for crossfading, ergonomics, and, of 
course, an unsprung joystick! The kinetic gates seem like a very nice 
bonus (I am curious as to how 'playable' this feature will turn out to 
be. I expect it to be lots of fun.) Thanks, Mr. Grenader!)

Best to all,

Tomas Everaert.
