Foot Pedal Interface
This board is used to generate note-on and note-off midi commands for
a two octave organ pedal board. Vanes are attached to the end of each
pedal. Pressing a pedal forces the vane to break the beam of a slotted
opto-interrupter. There are five of these boards, in three different
sizes, mounted at the back of a set of pedals. The board can be cut at
either column of jumpers.
White Noise Source
This white noise source is similar to the ARP 4022 noise module and
the Minimoog noise generator. The noise module is 0.5 x 0.625 inches.
The pinout of the header is +V,GND,-V,Output.
Four Pole Voltage Controlled Filter
All of these boards are custom products. Please contact iblocks for
customization and purchasing options.
This four-pole filter design is based on the Arp 4075 schematic. All the
components are surface mount except for the interface header.
