modulation generators (LFO, ADSR)

[mush]

Hey!

 

I m new in this forum, so i will have more questions than answers, sorry about that.

I was looking for modulation generators (LFO, ADSR) generated by a chip and i found on various forums people suggesting to use midiboxSID to do so.

I spent some time to read ucapps (i m already a bit familiar to this because i built a midibox with few encoders mounted inside a midi keyboard) and treads on this forum.

My project is to control analog modules like VCOs, VCFs, VCAs (which i already own) via modulators generated by the midiboxSID.

I don't need all options offered by this great project! (i heard about people stealing the idea and selling it, what a shame...)

 

So, i have a few questions :

 

- are the envelops and LFOs generated by the SID chip or by the Core module?

 

- how precise they are? (bits, hz) i want to avoid digital artifacts like steps and weird unwanted noises...

 

- how far is it possible to adjust the frequency of LFOs and differents times of ADSR?

 

- is there a midiboxSID V3 running on mios32 and LPC17? (and where is it?)

 

- do i need the C64 SID chip to make it work or not? will i have to change the code a lot?

 

- does the Core module has DACs to output the LFOs and ADSRs? or do i need to use the  AOUT Module?

 

- how many of them can i run on a single chip?

 

i have a lot of other things to ask but i thinks that's quite a good start!!

 

thanks in advance for your futures answers...

 

wish you a good day or night from France!! (BTW, sorry for my poor english)

MIDIbox CV 2 might become a better solution, because it is made exactly for this purpose: controlling analog synths with some digital modulators at a very high resolution and very high update rate.

This app is still only used by insiders, the documentation can only be found in this thread (no official project yet)

And the biggest drawback: currently it can only be controlled from an iPad; a CS is planned, but not implemented yet.

 

The official project will probably recommend a http://www.ucapps.de/mbhp_core_stm32f4.html board (also in progress), because the additional DSP capabilities might be advantageous, and the Audio output could also be helpful for whatever future features ;)

 

Best Regards, Thorsten.

thx a lot for the very quick response.

so the best thing for me to do is to wait that you come up with THE solution!!

that sound easy...

im not in a hurry , so ill keep an eye on it...

thx again!!
