UPDATE: June 2008 Be sure to check out Richard’s mods in the comments below.
1 Bass Drum (CH1)
2 Bass Drum (CH2)
3 Tom2 (click)
4 Snare (noise)
5 Snare (click)
7 Tom2 (tone)
8 Tom1 (tone)
9 Tom1 (click)
The toms and bass drum are made up of 2 sounds. A click and a tone. The snare is made up of a click and a noise wave. And i think the cymbal is just noise. You can wire up jacks to these points, with the jack’s ground going to the circuit’s ground for individual outputs, or you can wire up pots to these resistors for individual volume controls.
Mattel made an “accessory pedal” for the synsonics- a bass drum and hi hat pedal. The accessory jack is a 5-pin DIN jack, but don’t try plugging a MIDI cable into this thing. A better idea would be to make a custom cable with a male DIN connector on one end, and female 1/4 jacks on the other, so you can plug in standard drum trigger pedals. [EDIT: someone actually did this and says it works] Or you could bypass the DIN jack altogether, and wire up trigger jacks on the case (if you can find room).
5 – Ground
4 – Bass Drum trigger (connect to ground – pin 5)
3 – Hi Hat accent (connect to ground – pin 5)
2 – Sync Pulse Output: 16 pulses per quarter note (ppqn), 8V+, 15msec.
1 – Sync Pulse Output (Bass Drum): 1ppqn, 8V+, 15msec.
Important Note: The original diagram that was here had a pinout numbering system that conflicted with the pinout from the service manual. I have now changed the pin numbers to match the service manual. Also: the OUTSIDE VIEW diagram is looking at the front of the jack, and the INSIDE VIEW (from the service manual) is looking at the back of the jack. Thanks to RichardC64 for pointing this out!
(mp3)Synsonics DemoMP3 – 1.53 Mb – 0:50
I’m trying to play synsonics and bent sk-5 at the same time. Thom is playing bent touch n tell. This is a good example of the decay mod on the synsonics.
(mp3)toy analog acidMP3 – 4:00
Toy drum groove. featuring thom’s modded synsonics, q-bent tom drums & analog ‘beww’ machine’s feedback drones.
|Ok, i don’t even know where to begin. As you can see, I’m on the bottom of the board here. This might not be the easiest way to go about moding this thing. When you open it this way, you have to move the drum pads aside, and it’s a real pain in the arse to put it all back together. It might be better to go from the other side, but you do what ya gotta do.
I’ve marked 3 areas of the board. A,B and C. These areas seem to be where the most mods are. B contains the individual outputs. The above table has all the mods i’ve found (so far).
“AH (pot) B8 Tom1 synth vol” means connect a potentiometer between point AH and point B8 for control of the synth volume for tom 1.
“AG (output) nosie” means connect an output jack (hot) to AG (with jack ground to circuit’s ground) for an output of just one of the noise synths.
Experiment with different value pots. I used a 100K pot when i found these mods.
