discoDSP isn’t the loudest name on the market, and that’s part of what makes this release worth a look. The developer has just shipped Corona 7, a major overhaul of its hybrid soft synth that blends virtual-analog synthesis with wavetable playback. The feature list runs long — full MPE, a unison mode borrowed from the legendary JP-8000, an arpeggiator turned sequencer, 8x oversampling — and, crucially, the update is free for anyone who already owns Corona 6. In a corner of the industry that happily charges for every version bump, that deserves a mention.

A VA + wave hybrid with twenty years behind it
Corona is no newcomer. The synth has been kicking around DAWs since the mid-2000s, and the recipe hasn’t fundamentally changed: three oscillators that switch between analog modeling and wavetable playback, sixteen combine modes to marry them, two zero-delay feedback filters, three envelopes, two LFOs and an eight-destination modulation matrix. There’s a built-in effects section and, historically, SoundFont import — the detail that long made Corona a sample player in synth’s clothing.
That architecture sits halfway between a classic subtractive synth and a sound-design instrument. Nothing revolutionary on paper, but a coherent whole, light on CPU, and maintained year after year. It’s exactly the kind of tool that ages well: no chasing gimmick features, an interface you grasp in ten minutes, and a sound that holds up in a mix.
What version 7 actually brings
The v7 is more than a fresh coat of paint. The additions land on playability, modulation and render quality — the three axes that genuinely matter on a production synth.
MPE at last, and well integrated
This is the flagship feature. Corona 7 now accepts MPE (MIDI Polyphonic Expression): every note carries its own pitch bend, pressure and timbre axis, and all three streams arrive straight into the modulation matrix as sources. In practice, a Seaboard, LinnStrument or Osmose can sweep the filter cutoff on one note while another stays put — the kind of expressive playing that plain MIDI makes a chore. MPE zone, mode and pitch-bend-range settings live in the MIDI menu. The implementation is clean: you don’t bodge it, you route it.

Super 7+: the JP-8000 supersaw, built in
The new Super 7+ unison mode openly nods to the Roland JP-8000’s famous supersaw, that stack of detuned sawtooths that defined trance leads and big-room anthems. Done right, this kind of generator delivers instantly fat pads and leads without hand-stacking seven voices. It’s an expected addition on a VA that also has one eye on electronic music.

An arpeggiator that becomes a sequencer
The 32-step arpeggiator gains a sequencer mode with step recording and MIDI export. The distinction matters: you’re no longer just generating a pattern from a held chord, you can compose a sequence, capture it and export it as a MIDI file to rework elsewhere. For sketching a bassline or a lead motif inside the instrument, that’s time saved.

8x oversampling and playing comfort
On the audio-quality front, Corona 7 packs an 8x oversampling engine with a reworked decimator, paired with a Draft Playback mode that eases the CPU load while you work and reserves the high-quality render for export. There’s also live modulation display across the whole panel — handy for seeing what’s moving — and an Effects Lock that keeps the effects section across preset changes. Small things, but small things that smooth the workflow.
Price, formats and availability
| Item | Detail |
|---|---|
| Price | 149 € (free for Corona 6 owners) |
| Formats | VST3, AU, AAX |
| Platforms | macOS (native Apple Silicon + Intel), Windows, Linux |
| v7 additions | MPE, Super 7+, sequencer, 8x oversampling, Effects Lock |
Native Linux support, still rare among commercial developers, is worth flagging: it puts Corona in the small club of synths you can run on a studio machine under a free distro without an emulation layer.
My take
I’m wary of synths that push a major version every six months to justify an invoice. Corona does the opposite: patient development, additions that answer real playing needs, and an update policy that respects existing customers. MPE routed properly into the matrix is what separates a gimmick from an expressive tool — and here it’s done seriously. This isn’t the synth that’ll make you drop your desert-island instrument, but it’s exactly the sort of reliable, affordable building block that made going fully in-the-box viable. At 149 €, free for the faithful, there’s very little to fault.
