sid oscillator issues

hello

so i seem to only be able to control OSC 3 of the sid now. i am working on my max editor and when i attempt to switch the waveforms on OSC 1 or OSC 2 i get nothing. this wasn't happening before. might i have set something wrong on the SID ? i am using cc 32 to switch all the waveforms and cc 33-35 to set the individual channels. any assistance is much appreciated.

Hi Scott,

different things have to be taken into account:

  • ensure that mono or legato mode is enabled (and not poly mode)
  • if the pulse waveform has been selected, the pulse width should be > 0
  • if the oscillator output is routed through the filter, don't forget to enable LP, HP and/or BP

Best Regards, Thorsten.

thanks for the reply

the really odd thing is that if i turn the output WAY up i can hear the other 2 oscillators - but only under a huge cloak of noise. i am not yet storing patches in a bank stick so when i power down and then power up again shouldn't all the settings reset back to the defaults ? have any such inconsistencies been reported with the SID chip ?

once again - this was all working fine before - and then one day it just "changed"... my filter still has never worked - but i am going to swap out the filter caps and see if i made a part error on that one.

thanks

Reburn the PIC if you want, or if your using Jsynth load the ini patch to your SID

The SID has 1 internal patch which is stored even after power off.
