"DELTA DP-900 - 1985?

It happens that an instrument surfaces that no one's heard about or even seen before.
But it rarely happens that no one hasn't even heard of the manufacturer of that instrument.

Delta - what kind of brand was this?
Where were they?
Is this the only thing they developed?

M‑VAVE FM‑1 Review & Sound Demo – Fun Pocket FM Synth

video upload by dongchannel

"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."

Unsync - 3 Semi-Modular Analog Synths (0-Coast, Taiga & DFAM) sequenced by Hapax

video upload by 2-Minute Warning

"This time I wanted to experiment with a rather unusual setup: 3 semi-modular analog monosynths playing together. My goal wasn't to make the melody complex, but rather the rhythm. I tried to build a piece that sounds fairly simple on the surface, while hiding polymeters and polyrhythms underneath 😎

On paper, it doesn't sound like the most obvious setup: one synth for plucks, one for bass, one for percussion... and somehow convincing them to play nicely together!

The Hapax is sequencing the whole performance. At one point I activate its MIDI Euclid effect on the bass sequence to introduce a bit of rhythmic tension before bringing everything back to the original groove.

The DFAM is also receiving CV from the Hapax to transpose Oscillator 1 so that its pitch follows the bass line. Since the DFAM is usually thought of as a percussion synth, I always enjoy pushing it a little outside of its comfort zone 😉

Another thing I wanted to highlight was the Shape control on the Pittsburgh Modular Taiga. Throughout the jam, I gradually morph the bass timbre simply by playing with the oscillator shapes. It's one of my favourite aspects of the Taiga: even a simple bass line can evolve dramatically without touching the sequence itself. The same approach works beautifully for leads and other melodic parts too.

As always, this was performed in a single take. I do the mixing and mastering afterwards in Ableton Live, but I didn't edit or 'fix' the performance itself. What you hear is what was played."

Wavetables on the Akai MPC: OS 3.9 Turns Keygroups Into a Wavetable Synth

video upload by Keith Crosley

"The Akai MPC just became a wavetable synth! With the MPC OS 3.9 update (and the new MPC 3 desktop software), Akai added oscillators — including a wavetable oscillator with custom wavetable import — to Drum and Keygroup tracks. In this video, I walk through how wavetables actually work on the MPC: enabling the oscillator, installing your own wavetables, the format.json quirk, and a deep dive into sound design across more than a dozen wavetable categories.

To make this painless, I built the KRC MPC Wavetables Collection — 2,156 wavetables preformatted for the Akai MPC, just $10 — and added a free Akai MPC version of my Free Wavetables collection (1,600+ wavetables). Everything in the intro track (besides most of the drums) was made with these.

─── WHAT YOU'LL LEARN ───
How to enable oscillator/wavetable layers in MPC key groups (OS 3.9 / MPC 3)
How to install custom wavetables on standalone MPCs and the MPC 3 desktop software
The format.json requirement (samples-per-frame + frame count) and how to work around it
Designing sounds with up to 8 oscillators, crossfade-as-time morphing, and the mod matrix
A tour of 13 wavetable categories: Bézier, choir, split, polygonal, M-series, microwaved (Waldorf-style), phase distortion & more

Voidcontrol MIDI Releases e7 Unofficial Editor: DAW Integration for the GS Music e7

e7 Unofficial Editor - VST3 Demo video upload by Voidcontrol MIDI

"VST3 editor for the GS e7. Real DAW automation, easily build multitimbral patches, patch library, A/B snapshots, morph, and resizable UI. Windows 10/11. Available at voidcontrolmidi.com."

Press release follows:


Voidcontrol MIDI has released the e7 Unofficial Editor, a Windows VST3 plugin that lets you control and automate the GS Music e7 from within a DAW, just like a software instrument.

The e7 is a remarkable analog polysynth with a passionate community and a genuinely unique sound, but editing it properly from a DAW has often meant menu diving on the hardware. This editor was designed to make that seamless. All 88 of the e7's parameters are on screen, laid out to mirror the front panel, with real DAW automation on every control rather than just MIDI learn.

Features include:

Full parameter control: every one of the e7's 88 parameters on one screen, with authentic readouts for oscillator tune, tempo-synced LFO rates, and waveform shapes.

Real DAW automation lanes for every parameter.

A patch librarian: browse, audition, load, rename, import and export single presets, whole banks, or full instrument backups as standard .syx files.

Multi-mode support: edit 4-part multitimbral patches with per-part level, MIDI channel, voice allocation, and key/velocity zones.

A/B snapshots with an automatable morph slider.

Two-way hardware sync: pull the synth's current edit buffer into the editor in one click, with the editor recalling its state on project load.

Init and a musical randomizer for fresh starting points.

A resizable interface with onboard help.

A standalone version is also included for use without a DAW, working as a pure hardware controller that needs no audio interface.

The editor has been tested in Ableton Live, Bitwig, Cubase, Reaper, and Studio One, with USB and 5-pin DIN MIDI, MPE support, and a one-click All Notes Off panic.

"The e7 sounds incredible. I just wanted to see all of it at once, especially the multitimbral side," said Dave of Voidcontrol MIDI.

Voidcontrol MIDI is a small US-based developer making editors for boutique and classic hardware synths. The e7 Unofficial Editor is its third release, after editors for the Roland SE-02 and Oberheim OB-6. A macOS version is under consideration.

The e7 Unofficial Editor is available now at voidcontrolmidi.com for an introductory $30 USD through July 7, 2026, after which it returns to its regular price of $40 USD.

The e7 Unofficial Editor is a third-party tool and is not affiliated with or endorsed by GS Music. "e7" is a trademark of its respective owner.

Matt Barber - 80's in 80 seconds - Episode 5

video upload by Matt Barber - Sounds from The Sandbox

"Here is episode 5 of my series 80's in 80 seconds where I create an 80's synth themed track bed layering each part progressively in 80 seconds and then do a little improv jam along with it. I was able to integrate a few new pieces of gear on this one some of which I have been restoring and bringing back to life over the last few months including the Linndrum, Roland TR-727, Lexicon Model 200 reverb, and the Klark-Teknik DN780 reverb that is in the same vane as the AMS RMX16. I finish the jam with the Roland MKS-10 which was the first rackmount MIDI sound module released by Roland in 1984 that eventually led to the more infamous MKS-30, MKS-70 and, MKS-80. It is a 16 voice velocity sensitive EP/Clav/harpsichord type module with chorus, flanger, tremolo and a brilliance slider to control the tone of the 16 iconic Roland IR3109 filters it has on board. Sounded so good after I got it that I bought a second. Hopefully I can do a more in depth video on this in the future. For now enjoy episode 5!"

Sequential Fourm | Ambient synth performance

video upload by Jay Hosking

"Please support my work on Patreon: / jayhosking
A live synthesizer jam performed entirely on hardware, with the Fourm at the centre.

The amazing Devin Belanger (‪@devinbelangermusic‬) aka Miles Away (‪@thisismilesaway‬) was kind enough to lend me his Sequential Fourm. Thank you, Devin! If you haven't checked out Devin's amazing channel or his music, please do so!

The Fourm is Sequential's entry-level analog polysynth, as far as I can tell. It has four voices, which is somewhat limited but OK for many circumstances, and sounds (to my ears) as good or better than any other Sequential synth I've personally owned. (Note: I haven't had a Prophet 5/10 and Devin swears by that thing.) So if the sound and a decent workflow are all that matters for you, and four voices is enough, then this thing is a no-brainer.

That said, its main feature is its poly-aftertouch keybed, which allows for you to modulate sounds by pressing into each of the keys. I love polyAT, and the Hydrasynth's polyAT keybed was tremendously inspiring to me. That said, I really struggled to get the polyAT to feel right for my playing. The biggest issue was a discrepancy between how the black keys responded versus the white keys. For the white keys, I could get a great linear aftertouch response, but with the black keys, it would often quickly ramp from 0 to 100 in a way I couldn't control. This could be something I get better at, or maybe it's this particular unit, or maybe it's just an issue with my skills. But ultimately, I found that the polyAT wasn't for me.

The sound, however, most certainly was. This thing sounds amazing. Here, I ran it through the Walrus M1 Mk2 (for auto-panning) and the Empress Reverb (for reverb), and then into the Soma Cosmos for looping. The first half was the more traditional "song" aspect, but truthfully, the second half wandering was my favourite. I could listen to a synth like this all day.

Thanks for listening.

Recorded live to a stereo output, with EQ, compression, and limiting on the master.
