Über / aboutDer Microwave war der erste Waldorf Synthesizer (1989). Er hat innen (wie 4 Jahre später auch der Waldorf WAVE) den von Wolfgang Palm (Mister PPG) entwickelten ASIC, der die meisten digitalen Funktionen der Soundgenerierung der PPG wave Serie auf einen Chip integrierte.
The Microwave was the first Waldorf synth (1989). It got a ASIC designed by Wolfgang Palm (Mr. PPG). These feature most of the digital sound functions of the PPG waves. They were later used inside the Waldorf WAVE too.

- 1 ASIC (designed by Wolfgang Palm to reduce most of the PPG wave digital board into a single chip)
- 1 Motorola MC 68000 P8 CPU
- 8 CEM3389 VC Signal Processor (4 pole VC lowpass and 4 VCAs) for revision A.
Revision B had the Curtis CEM 3387 (the same filter as found in the big Waldorf WAVE, but somewhat not sounding that smooth here).
- 8 CEM 5508H Octal Sample & Hold
Filter calibrationAny MW1 users who have a working unit: DON'T DO THE FOLLOWING!!
To tune the filters, you have to go into the Service Mode.
Again: all others shouldn't do that, **only** if they experience *major* tuning problems.
- Press Mode and switch on the MW. As soon as you can read "Welcome to.." release the Mode button.
- Press OK to confirm the warning message.
- With the Mode button, step through the pages until you read "Filter Test"
- With OK you can toggle each of the eight filters on and off.
- With the alpha dial, you can tune the filters. I think you should try 440Hz, but if you can't reach it with one or more filters, try to find a close frequency and tune the other filters to that, too.
- When you're done, switch the MW off and back on. Now the filters are tuned again.
