GRP Synthesizer, an Italian Boutique company, teases the upcoming A10 flagship Synthesizer with effects and sequencer.
The Italian developer Paolo Groppioni, aka GRP Synthesizer, has produced high-quality handmade synthesizers for many years. With the GRP A1, they released their first mono synth à la Doepfer Dark Energy last year, which is significantly more affordable than the previous products.
This digression was probably only brief. GRP Synthesizer is currently teasing the A10, a new flagship semi-modular Synthesizer.
GRP Synthesizer A10
The A10 Synthesizer is still fully developed and appears only in the design phase. However, we can already see that the upcoming GRP Synthesizer A10 will surpass the current giant A8 synth.
The synth, measuring 1200 mm x 560 mm, will consist of three sections: a semi-modular synth, the R24 sequencer, and several effects.
A10 will feature four classic VCOs with PWM, hard sync, cross-mod, and linear/exponential FM. Additionally, you can find a sub-oscillator, a noise generator, a ring modulator, and an external input. All this goes into a multi-channel stereo mixer. The filter section is also packed with features.
There are two filters, each offering a choice of two distinct circuits: transistor ladder or Vactrol in filter 1, and diode or SVF in filter 2. The transistor ladders also offer five slope variations, and the SVF has five modes.
The filters can be operated in series and parallel, are overdriven at the input, and can be modulated by numerous sources, including resonance. A wavefolder can be placed before or after the filters. Nice, this brings harmonic-rich, West Coast sounds to the GRP synthesizers
Then, it will also have an impressive set of modulation, including three multi-wave LFOs, two DAHDSR envelopes, a sample & hold generator, and more. You can play synth engine in mono, dual, and split modes.
Effects & Sequencer
The second section of the GRP Synthesizer A10 contains an analog effect section. In addition to the analog wave folder, it houses a stereo BBD delay with independent sync and modulation for both channels, a dual triple resonator with LFO, a dual voltage-controllable phaser with 6 or 12 stages, and a stereo spring reverb.
This already sounds tasty and probably sounds pretty epic. Further, it has an integrated sequencer based on the standalone R24 hardware unit with three rows of eight steps. This expanded version can combine the rows and offers ratcheting, step repeat, clock division, and more. A MIDI-controllable arpeggiator is also onboard and can be used parallel to the sequencer.
The GRP A10 Synthesizer features a patch matrix with numerous inputs and outputs, making it a semi-modular instrument. Two CVs can also be assigned using switch knobs. On the connection side, we can see balanced XLR audio outputs, MIDI DIN, and USB.
First Impression
This is the first information available so far about the new GRP Synthesizer. It looks like a true flagship semi-modular synth. I’m excited to hear how it will sound, especially in combination with the analog effects.
GRP Synthesizer A10 availability and price are TBA.

Loved the A6, I’ll be picking up one of these for sure.
Price tag will be around 10k tho.
