Hi there : )
Built a Shruthi a few years and just recently got it out after not using it for a while.
Worked ok before but now the filter is acting very strange - I’m getting no cutoff sweep, just cuts out completely around 100 (from 127) and the oscillators are only audible if the resonance is right up, but there seems to be no actual resonant peak. The filter env mod needs to be above 4-5 to hear anything too. When I lower the cutoff, there’s no change, then just cuts out to nothing via mildly distortion. Same with lowering the res with cutoff fully open.
All other setting are initialised - amp/filter env fully open, no modulation (aside from amp - env2 on max), just one osc on a saw or squ to test etc. Tried various setting and just seems to be the filter that’s acting odd. Have also tried different PSUs with the same result.
Any ideas of a fix? Would love to get it working again, even hearing it without the filter not sure why it’s been away so long!
Thanks : )
