The M.3030 part of PG Mini is a 3-part modular synthesizer that is designed for creating various sounds and can be used for creating music and soundscapes. It consists of three separate modules, which are the M.3052 Monotron, M.3054 Multi-Rack, and M.3055 Connector Board. The M.3052 Monotron features the classic 5-pot diode ladder low-pass filter found in the classic Roland synchronizer with additional features like an oscillator, audio input, and several controls. The M.3054 Multi-Rack module provides sequencing, sequencing via triggers, arpeggiation, and a wide range of effects. The M.3055 Connector Board is an advanced patch matrix that provides connectivity between all parts of the PG Mini. In addition to the three main modules, it also includes a power supply and a MIDI interface that integrates control of all modules into a single unit.
