Our quest for the origins of analogue synthesizers
The new PS-3300 delivers an astonishingly rich sound - equivalent to 144 MS-20 units - while remaining true to the architecture that defined the original. At its core are three PSU-3301 sound generator units, just like the PS-3100. Each unit includes a VCO, VCF, VCA, and EG, plus powerful modulation tools: two LFOs (modulation generators), three voltage-controllable bandpass filters (resonators), and 12 independent tuning knobs for microtuning - an expressive capability only possible with fully polyphonic synthesizers.
The three PSU-3301 modules operate as independent layers, with overall balance controlled by the PSU-3302 module on the right. This versatile section includes a sample & hold for stepped control signals, a global EG (GEG) for shaping overall dynamics, a voltage processor for fine-tuning control signal width and phase, and junction jacks for distributing signals. Despite its deep modular flexibility, the PS-3300 is semi-modular, with internal connections that eliminate the need for patch cables to produce sound.
The interface preserves the exploratory spirit of the original, complete with unconventional controls and parameters whose naming reflects the era of its design. Abundant patch points offer creative routing possibilities for control signals, inviting users into the same trial-and-error process that inspired early electronic musicians.
One standout feature is the ability to shape sound using the three-band resonator - applying LFO modulation to achieve phaser, wah, and other dynamic effects. Long before dedicated effects units became standard, this innovative design allowed for vibrant, evolving textures. With these tools, the PS-3300 invites users to rediscover the joy of sonic experimentation and experience the forward-thinking philosophy that helped define a new era of synthesis.
