M‑VAVE FM‑1 Review & Sound Demo – Fun Pocket FM Synth
"How does this under‑$70 FM synthesizer perform? Check out this video for a full feature walkthrough, sound demos, and my honest thoughts.
I first spotted the M‑VAVE FM‑1 at this year's Guangzhou Musical Instrument Fair, and picked one up shortly after for about 300 RMB (around $60). The packaging is minimal, the unit itself is compact (16×9 cm), yet it packs everything you'd need. Connectivity is surprisingly generous, with both wired and wireless MIDI and audio support – really well‑equipped for its size.
Inside, you get a 6‑operator FM engine, essentially a recreation of a classic 1980s Japanese synth. It comes with 128 preset sounds, plus an effects chain, a 16‑step sequencer, an arpeggiator, and deeper editing tools. Pair it with an external MIDI keyboard and the playability expands even further.
Are there minor software quirks? Sure. But at this price, they're hardly worth mentioning. Compared to other portable sound gadgets in its class, the FM‑1 is just plain fun. And for the money, the build quality and feature set far exceeded my expectations."
"This is the instrumental version of the song 'Fibrillomicina.'
I love electronic music and compose and produce it in my studio.
I love both vintage and modern electronic instruments. In this song, I used modern synthesizers.
--The instruments I used are:
--GRP-A4 synthesizer for the automatic bass
--GRP synthesizer vocoder V22 for robotic voice part
--Moog VoyagerXL for solist part
--Oberheim OBX-8 for solist and pad parts
--Waldorf Quantum for solist part
--Nord Grand for piano part
--Solina String Machine for pad
--Erica Synths Perkons HD-01 for hypnotic percussions
--ANTELOPE Orion 32+ Gen 3 as audio interface
--SOLID STATE LOGIC Sigma Delta for summing all analog audio traces
--Steinberg Cubase 15 as DAW and Wave lab 13 for final mastering
Enjoy the song!
This is a pre-release. The official release is on the 26 of June on the main web platforms of music distribution.

"The limo stops in Eagle Rock to pickup LA locals Automatic. Equipped with multiple synths, they perform a live version of 'Mercury' from their 2025 album Is It Now?
"Simple melodic ditty. just dusting off some oldies. SH-1 sequenced by a Korg SQ-1 in random mode. Initial drone sound is SH-1 (overdubbed), then following drone is from a sustained note on the RS-202 using the Vintage Synth Automatic Key Sustainer (electricians tape). Some verb in the mix, and delay on the SH-1.
I love vintage analogue synths, they often have a lot of character, but they also have their practical drawbacks, such as maintenance! My SH-1's sliders need some love, but the keyboard tracking's gone haywire (or should that be J-wire?) and the unfortunately named 'Bender' has transformed itself into a 'random source of uncertainty''... or a garbled note generator.
The RS-202 is working well though... so far, but changes in circumstances mean it's probably destined for the great online auction in the sky... or 'cloud'... whatever. It's a lovely-sounding thing, but like most vintage string synths, it's huge and doesn't do a lot. But, what it does do, it does well, and that chorus... Roland have a great lineage there.

"Great and powerfull analog synth from 70's This one is in excellent cosmetic conditions (I am the 2nd owner and always kept in free-smoked studio as the 1st owner too) the Pro-One can generate many of the same sounds as the Prophet-5 and Prophet-10, capable of supremely punchy bass lines and distinctly ripping leads, fueled by two VCOs, referred to as Oscillator A and Oscillator B. he Pro-One has extensive modulation provision with three modulation sources available, featuring Filter Envelope Generator, Oscillator B, and a separate LFO. Each can be mixed and routed for either Direct or Wheel-controlled modulation. On the back of the unit, there are Audio, Filter CV, Gate/CLK, and CV inputs. Other features include a 40-note sequencer, an arpeggiator, Pitch and Mod wheels, Repeat and Drone switch, Single and Multiple-triggering keyboard modes, and the unique Automatic Glide, enabling one-handed complex, 'tuned' pitch bending sounds."
"Published the very same year electro-industrial pioneers Kraftwerk released their breakthrough album 'Autobahn,' here's a wonderful, rare book covering virtually everything you ever wanted to know about music synthesis and reproduction.

"ITALIAN In questo video mostro come suonare contemporaneamente due sintetizzatori KETRON-SOLTON PROGRAMMER 24 sincronizzati tra loro e poi come far suonare la linea di basso di un PROGRAMMER 24 da un sintetizzatore MINIMOOG DODEL D
Il Solton Programmer 24, lanciato nel 1985, è riconosciuto come uno dei primissimi strumenti a introdurre il concetto di arranger automatico nel mercato delle tastiere, tanto da essere spesso definito 'l'apripista' dell'intero settore. Questo strumento, prodotto dall'azienda italiana Ketron (con il marchio Solton), è considerato una pietra miliare nell'evoluzione delle tastiere arranger.
Impatto Culturale: è stato soprannominato 'Italian Disco Machine' per il suo ruolo nel plasmare il suono della musica Italo Disco. Il Programmer 24 non è solo un pezzo di storia per gli appassionati, ma è anche al centro di iniziative come 'Arranger Legacy', un progetto web che mira a preservare la memoria di questi strumenti iconici e dei loro creatori.
Il Solton Programmer 24 è una workstation analogica italiana del 1985, famosa per il suo suono Italo Disco, che combina una sezione ritmica PCM a 8 bit (con uscite separate), bassi analogici, arrangiamenti automatici e sequencer, offrendo un suono vintage caldo e funzionale per produzione musicale. Include funzionalità avanzate per l'arrangiamento, sequencer polifonici e monofonici, MIDI, e interfaccia a nastro, rendendolo un pezzo da collezione apprezzato per il suo 'carattere anni '80'.
"A vintage Elka OMB 5, the programmable arranger / rhythm unit specifically designed for Italo Disco, in perfect working condition and in mint cosmetic shape. The deal includes its ultra-cool original bag, owner’s manual, and a Song RAM cartridge. UPS fast delivery and professional packing guaranteed.
Released in the mid-'80s by the Italian manufacturer Elka, the OMB-5 (One Man Band) is a powerful yet easy-to-program arranger featuring a rhythm unit, a bass channel, and two accompaniment tracks.
RHYTHM UNIT
The OMB-5 comes with 20 preset rhythms (Disco, Funk..), each with four variations, one of which is fully programmable by the user — for a total of 20 storable custom drum sequences. Each preset rhythm also includes two fill-ins, an intro/ending, and a dedicated break.
The 32 drum sounds are the same as those found in the iconic Elka Drumstar 80: a cool selection 8-bit PCM drum samples, a perfect mirror of that unmistakable '80s aesthetic. The rhythm section is extremely easy and intuitive to program, and the ability to edit individual drum sounds within a recorded sequence using a single 'cancel' button is simply brilliant. A true example of vintage Italian clever design.
SOUND SECTION
The Elka OMB-5 features a powerful and flexible sound section totally based on FM synthesis and divided into three blocks:
Bass (6 voices) Presets 1 (12 voices, 5-note polyphony) Presets 2 (12 voices, 5-note polyphony) Each block supports 6 arrangements per preset rhythm, with Arrangement 6 fully programmable, allowing up to 20 custom sequences to be stored per block (Bass, Presets 1, Presets 2).
Presets 1 sounds : STRINGS, BRASS, ELECTRIC GUITAR, BANJO, JAZZ GUITAR, MARIMBA, VIBRAPHONE, CLAVINET, ORGAN 1, PIANO 1, SYNTH 1, SYNTH 2
Presets 1 sounds : STRINGS 2, STRINGS 3, BRASS 2, PIANO 2, HARPSICHORD, ELECTRIC PIANO, ORGAN 2, CLASSIC GUITAR, CELESTE, HARP, SYNTH 3, SYNTH 4
COMMON FEATURES (All Sections)
Volume and sustain length adjustable via dedicated sliders Usable in manual play or as part of the automatic accompaniment Custom sequences storable in Arrangement 6 for each preset rhythm"
