The Pulsar-23 from Soma Laboratory is a patchable, analogue
Instead of the chaser programming common for drum machines, the Pulsar-23 is played by means of loop recorders, of which there is one for each track. The four loop recorders are oriented to the internal clock generator, which also has divider values, and to the incoming MIDI clock. In addition, the four voices can be addressed via the MIDI interface, various CC commands are available as patch points.
More than 100 patch points distribute control voltages, gates, audio and clock signals to any signals inside and even outside the Pulsar-23. All patch connections are made with crocodile clips, which has the advantage that many connections can be made in a small space. For the integration of external equipment such as a modular system, there are eight bidirectional connectors for 3.5mm jack plugs on the front and another six bidirectional connectors for 6.3mm jack plugs on the rear. The large jack sockets could be used as individual outputs for connection to a mixing console, among other things.
