Thanks Thorsten! I will stick to the reed relays. :)

Hi! I have two synths I would like to be able to control wirh MIDI. Both synths have matrix-type keyboards. I have seen examples of how to use reed relays for every key and that is one option, but is it possible to connect to the matrix (pun intended) to control these synths? How can this be done, didn't find any example of this, just how to read keyboard matrices, not the other way round. Thanks for any help in advance! - Mikael

Thanks for all the help, I got this working fine. I'm attaching the frequency table for A4=432Hz if anybody else wants it (probably not). :) This is for version 1 of Midibox sid, I don't know if this file is different for version 2. sid_frq_table.inc

Thanks a lot, yes, I figured later that it wouldn't take so much time when the formula was in the specs. Good to know about the rounding errors!

Sorry nILS, I was studying the SID specs now and the inc file, I would be very thankful again if you can answer two questions. :) Some values in the frequency table in the inc file differ from the SID specs, why is that, is that something I have to take into account when re-tuning? I know this is a VERY small difference but... For example 0x0112,0x0122 vs 0x0112,0x0123 Secondly, the specs go down to 0x0112 (C0), but the inc file goes lower, do I need to change these, these notes are so low anyway aren't they? Thanks for your patience!

Ok, thanks for the quick answer. Here is a link that will answer your question: http://www.schillerinstitute.org/music/rev_tuning_hist.html

Hi! I have been tuning my guitars and synths to 432Hz instead of 440Hz. Is there a way to this on the Midibox SID? Thanks in advance!
