It took a long time but the Outer Space Sounds Mostro FM, a portable FM Synthesizer is available now for pre-order
Already in July 2017, I reported about the company Outer Space Sounds and the new Mostro FM Synthesizer. It has now taken two years to complete this new portable synth. A little downer: you can only pre-order it now, shipping starts later. Outer Space Sounds Mostro FM is a 4-voice polyphonic Synthesizer that is based on a simplified form of FM synthesis, no classic DX7 operator algorithms, etc. You can operate it like a subtractive synth.
Each of the four voices features its own envelope, LFO, and sub-oscillator. Each voice is based on a sinusoidal carrier/modulator system that is accessible from the interface with carrier modulator ratio, modulation index, and feedback. Actually, the well-known parameters of FM synthesis.
Modulations: Envelope & LFO
Each voice of Mostro FM features its own envelope that can be routed to the mod index, ratio, and feedback. The envelope generator routes can be set independently for each parameter or in all possible combinations.
Besides the envelopes, each voice also offers an LFO (freewheel or sync) that can be routed to the same three parameters (mod index, ratio, and feedback) but also to the carrier for a vibrato-like effect. LFO routes can be set independently for each parameter or in all possible combinations. So everything is very simple and easy to understand.
Mostro FM features an integrated delay effect processor at the end of the signal flow. It includes parameters for time, feedback and effect send.
There is also a glissando parameter that controls both the polyphony of Mostro and the time of the note slide in mono mode.
Mostro FM comes with a MIDI looper that allows you to record sequencer either from the internal keyboard or from external MIDI. Also, it offers an onboard keyboard made with thick black buttons that can be used for notes with different scales or chords. The keyboard can also be transposed by semitones.
A nice addition are the 5 CV inputs: gate, pitch, modulation index, radio & feedback with which you can control your synth also from other hardware devices like modular synths. For example, you can edit the engine further with other modulation sources such as LFO or envelope. Own sounds can be stored in up to 100 presets and copy them from/to a computer via USB. More space would have been better.

An interesting portable FM Synthesizer that can score above all by its simple operation. For the demanded price, however, it will be a little harder to succeed, especially in times of Korg Volca FM, PreenFM2 and so on. Nonetheless, Mostro FM an interesting new synth that is different from a classic Yamaha style FM synth.
