Hallo,
Hier is een beschrijving van de modificatie die je wilt uitvoeren:
The mode switch (play/write) is a 4 pole, double throw switch. One pole
of the switch changes whether the clock comes from the buttons/foot pedal
(for write mode) or off of the clock flip flop. Out of this switch, the
clock goes to the counter and to clock enable on the SRAM chip
As luck would have it, the switch (play/write) goes out into one of those
bare metal jumpers on the circuit board. All it would take would be this.
1. cut the jumper going to chip enable on the RAM.
2. cut the jumper carrying the clock to the hi hat switch
3. add a wire from the far side of the cut to the CE to the far
side of the hi hat switch jumper.
4. Put a jack in so that it makes and breaks the connection
between the play/write switch and the far side of the CE jumper.
This jack is now an insertion point for a 4 PPQ clock pulse. You
can probably plug a trigger out from a TR X0X right into this jack,
and program the X0X to send a trigger on each 16th note.
Ik heb hem zelf nog niet geprobeerd want mijn DR55 is kapot. Maar het ziet er allemaal niet al te ingewikkeld uit toch?
Succes ermee
P.S. als iemand weet hoe er een Sync input op en Electro Harmonix Rhythm 12 gemaakt moet worden, dan zou ik dat heel graag horen.
