[Bluemusic-users] BSB: Mod Matrix, Step Sequencer

[Steven Yi <ste...@gm...>]

Hi All,

I was catching up on reading Computer Music Magazine and saw a review of
Dmitry Sches's Diversion.  I was watching the CM video here:

http://www.dmitrysches.com/diversionfx

and had the thought that BSB would be nice to have a Mod Matrix and Step
Sequencer.  Some thoughts:

* The Step Sequencer could either generate code to handle creating an
ftable, writing to it, and reading from it into a variable.  BSB coding
then would be simply using the variable as other widgets, such as:

aout vco2 <amp>, <stepSeq1> * kpch

Does this sound good? An alternative would be to make it just generate an
ftable, but I think the above would be more immediately musically useful.
Also, I guess I'd need to figure out a way to sync to tempo, which I think
I could do by generating some tempo variable (another feature that would be
globally useful I think for effects, etc.)

* For a Mod Matrix, I had come up with:

-2 lists of sources and targets, user defines from Widget Properties, would
be names of variables
-<mod_matrix_1> - inserts code for handling mod matrix (may use a generated
UDO for tidier output)
-user responsible for generating source signals and using target signals
-<mod_matrix_1> - generated code will initialize all variable at start of
instrument

for example:

kenv  adsr <attack>, <decay>, <sustain>, <release>

<mod_matrix_1>

asig vco2 <amp>, <pch>
afilter moogladder asig, <cutoff> + <cutoffMod>, <res>


The matrix could allow multiple modulation sources to a target. I'm imaging
something similar to the one in DiversionFX with a source, amount, target,
but would be a non-fixed list with a [+] button to add more modulations.


Any comments appreciated!
