This one was spotted and sent in via M Me.

This appears to be the first one to be featured on the site. Also see the Dynacord ADD-two.

From the listing:

"Here comes the rare keyboard version of the ADS, namely the ADS-K, under the hammer!

The ADS/ADS-K dates back to 1989 and raised the 16-bit bar a little higher with 20-bit converters. On the one hand, the ADS ties in with Dynacord's drum sampler history and, on the other hand, with their PA products (the well-known DRP-20 dates from the same time).

Extremely slick 80s design. Is - for my taste - only topped by the white version. But I've never seen them for sale. But the black version is also impressive. Who owns a Dynacord keyboard!?

Can also be used as a master keyboard due to the good synth keyboard and the large contact surface for computer keyboards or similar.

The features:
- 16bit with 20bit D/A converter
- Stereo sampling
- 16 votes
- 2MB, expandable to 8MB
- reads S-900 floppy disks (but I was never able to try it due to the lack of the sampler mentioned)
- Re-sampling (can sample itself)
- Additive synthesis with 64 harmonics
- Modulation matrix (see pictures; That's right, we also know it from another device, especially from the ramp generators. The software was said to have been programmed by the same gentlemen.)
- Internal mixer with loop-in path
- Individual outputs
- SCSI connection (I haven't been able to try that before, but it should still work)
- Good synth keyboard with effective dynamic conversion
- more features: see Internet

Unfortunately, the 33 years have left the following traces:

- The top two buttons are broken and beyond repair. I took them out of service and temporarily glued them on for cosmetic reasons. Didn't turn out that well - you can see a slight difference in height in the pictures. I hope the construction survives the transport.

- The upper right segment of the right 7-segment display is defective. You can see that in the pictures. "00" should be displayed. But that doesn't matter when playing, because you primarily look at the display and the button labels.

- The lower octave keys are slightly yellowed.

Scope of delivery:
- Dynacord ADS-K
- Original box
- Power cord
- Disks with sounds (unfortunately some of them are no longer readable)
- Leftovers/components of the two defective keys"


  1. Dynacord ADS-K looks as if it is trying to be an Ensoniq K2000 if that makes any sense.
