Pictures of the DR-110s:

• Gate inputs (on 9 pin D-sub)
• Mute switches & gate LEDs
• Volume controls for each voice
• Bass Drum: pitch and "oomph"
• Snare Drum: Impact Pitch, Snappy Level and Snappy Decay
• Hi Hats: Filter and Open Hat Decay
• Cymbal: Filter and Decay
• Hand Clap: Filter and Decay

• Gate Outputs (on 9 pin D-sub)
• 12ppqn clock input, start/stop inputs

This is my newest incarnation of the DR-110 sequencer. The biggest improvement over it's predecessors is the addition of MIDI sync using the DIN-Sync chip available from Blacet Labs. I also added 12ppqn clock output and start/stop outputs for syncing the Generation 1 DR-110. The stock voice board is still inside, so I added mute switches to each of them for a little more control. Finally I added 2 sets of gate outputs: a 9-pin D-sub on the rear and 1/8" jacks on the face.

• 2 sets of gate outputs (on 1/8" jacks and 9 pin D-sub)
• Mute switches & gate LEDs for internal sounds
• MIDI sync (using Blacet Labs DIN-Sync chip)
• 12ppqn clock output, start/stop outputs

As you can see, I've really spent a lot of time on the case for this one. The box is oak with a pecan stain and several coats of polyurethane. The top and bottom panels are 1/8" aluminum (I cut that opening by hand!). The faceplate was printed on yellow paper with my inkjet printer, then laminated both sides. I glued it to the front panel with 3M #77 spray glue.

Now we're cookin'. Obviously, this one's not quite done yet. I've prototyped all of the features listed, and I'm very happy with this machine. I'm currently in the process of doing the final faceplate wiring, and I'm rebuilding a few of the circuit boards with some last-minute changes. As soon as I have the money for a parts order I'll be finishing this one up.

This machine is the prototype of a machine I'm building for my friend RJ. There are some really great features here. Per-voice accent is a big one (each direct output has it's own accent circuit). You don't lose the "magic" of the DR-110 when using the individual outputs. I've added CV control to the pitch/filter of most voices (the jacks are at the rear edge of the faceplate) and there's a CV level knob (yellow) at each destination

The red knobs are pitch or filter frequency, yellow is modulation level, green is decay and blue is volume. The silver bolt in the middle of the snare is an "oops"... I drilled an extra hole by accident. Maybe I could use it as a body contact?

• 2 sets of gate inputs (on 1/8" jacks and 9 pin D-sub)
• Mute switches & gate LEDs for each voice
• Volume for each voice
• Bass Drum - pitch (manual and CV control)
• Snare Drum - impact pitch, snappy decay and snappy level
• Hi Hat - Filter (manual and CV control), decay
• Cymbal - Filter (manual and CV control), decay
• Hand Clap - Filter (manual and CV control), decay
• Jack field containing Direct outputs (post fader) and mixer inputs
• Per-voice accent - signals at direct outputs are accented!
• Diode clipper distortion (with hard clip / soft clip switch)
• Noise inputs for HH and CY (to use external noise sources)

Again, this one is oak with aluminum panels and a laminated paper overlay. It joins to the sequencer or a MIDI-to-gate interface with a 9 pin D-sub cable (or individual 1/8" cables).

The blank panel on the right is the future home of an LFO, envelope generator, and a new noise source. I'll probably bring this baby into the studio for a while before finishing the "sidecar" however. It's way too much fun to leave it in the workshop.
