| Initial Inspection | OK - silk messed a bit | |
| Initial Technical Test | VCF | CV2 signal issue round Jack |
| Initial Technical Test | ADSR | OK |
| Initial Technical Test | WaveFolder | OK |
| Initial Product Test | VCF | Not working due to missing Caps |
| Initial Product Test | ADSR | OK |
| Initial Product Test | Wavefolder | Works nicely |
| Test | Detail | Status |
|---|---|---|
| Product Test | CF | VCF - working ok after botch'ed caps added - no self osc |
| Product Test | ADSR | Works fine after added 100k resistors instead of 0R across 100KB pots |
| Product Test | Wavefolder | nice - no adjustments |
| Quality | VCF | Needs tweaking |
| Quality | ADSR | ADSR interacts when turned all the way down |
| Quality | Wavefolder | Nice |
| Long Term Product Test | ||
| Power Draw | VCF | 24mA |
| Power Draw | ADSR | mA |
| Power Draw | Wavefolder | 7mA |
- Missing signal path for CV2 on PCB
- Missing 2 caps from C207 to R226/227
- C214 should be 1206 (its a bit difficult to find 22u 0805 in 16v)
- C211 and C212 should be 1206 or bigger (10u 16v potentially sounds better than 0805)
