The ALLEYKAT gets a front panel.

"First and flawed test build of the Alleykat module.
Nine lives - no regrets......

Completed the next schematic revision today ready for submission to fab. In doing so i ended up spending an hour on this flawed test piece knocking this up for a bit of fun.

When you consider how good it sounds (in a c64 kind of way) in it's current state, it becomes quite obvious how cool it will be when the filter is online and all the parameters are active. The test boards had numerous errors on them which have rendered the ring/sync and octave hopping inactive. The filter cutoff and resonance were also mis-routed in the schematic which rendered the filter unusable.

Swinsid in circuit this time. Does a decent enough job, but i've yet to see how it performs in comparison to a real SID or a superior clone when the ring/sync and filter come into play. The only difference i hear using just the waveforms and pwm compared to the usual 8580 i use for testing is that the swinsid doesn't sound as bright.

With a bit of luck i've fixed everything that was wrong with the first attempt and the next revision will work properly."
