Discovery Pro 9.5 plus four new updates

Discovery Pro is a virtual analog synthesizer and sampler with 4 layers, 12 oscillators, 16 filter types including Nord Lead 2, Moog Ladder and Oberheim SEM models, SFZ/WAV/SoundFont/DWB/Bliss and Nord Sample Library support, PADsynth re-synthesis and Nord Lead 2 SysEx import/export.

Version 9.5 adds a zoom window for the Gate and Mod sequencers, with curve editing, a bipolar mode and an OSC1+2 pitch destination. The Nordic filter is rebuilt from the Nord Lead 2X hardware, and the filter menu is split into models and modes.

Sequencer Zoom Window

• The Gate and Mod steps open in a large editor that fills most of the panel, with numbered steps, beat lines, single unit edits and Shift+drag rotate. The Gate window shows GATE, RETRIG and NOTE OFF rows.
• Curve mode for the Mod sequencer: double-click adds or removes a point, drag a segment to bend it. The curve is written into the 32 steps and shows on the main display with a glowing dot as the play position.
• Bipolar mode runs Mod steps from -100 to +100 around a centre line, so the modulation can go below the knob position or the played note.
• OSC1+2 destination moves both oscillators with the Mod pitch sequence, for arps, bass lines and whole-voice pitch moves such as a tape stop.
• LINK shows the Gate and Mod sequencers as one, and Shift+click writes retrig and note off marks from the pattern.
• New Mod presets in six folders: Curves, Pitch Curves, Pitch Sequences, Filter Steps, PW and FM Steps, and LFO.

Filters

• The Nordic filter runs the Nord Lead 2 filter equations (two cascaded state variable filters) at the hardware's 98.2 kHz clock, with the NL2 cutoff table, resonance law, per-mode mixing and clip levels. The response matches the hardware within 0.3 dB up to 20 kHz. Sounds already using the Nordic model will sound different.
• The filter popup is split into a Model submenu (Zero Delay, Nordic, Ladder, Ladder X, Ladder Y, SEM, SEM Raw and Classic) and a list of modes. Presets, banks and automation load as before.
• Auto Switch LP switches low pass layers to a chosen model and keeps their cutoff frequency. Swap > Bank switches every layer of a bank to one filter model.
• The Nord Lead 2X, Nord Lead 2 and Lib 1 to Lib 4 factory banks use the Nordic filter and the Retro oscillators.

This update is free for all Discovery Pro 8.x and 9.x customers. Discovery Pro is available for Windows, macOS and Linux in VST, VST3, AU and standalone formats.

Other recent updates:

Bliss 3.26

Version 3.26 adds Gigasampler (.gig) import and an import picker for large disk images.

• Export Bank to Individual Programs writes every program as its own .zbp file.
• Velocity Curve in the Play Mode menu, saved per program.
• Third party imports run in the background with a progress bar and can be cancelled.
• Fixed Akai S3000 samples being read 42 bytes late, which added noise at the end.

This update is free for all Bliss 2.x and 3.x customers.

Corona 7.1

Version 7.1 improves oscillator hard sync and the oversampling decimation filter.

• Sync reset lands between samples, removing inharmonic sidebands around the slave partials.
• New half-band decimation filters, flat to 20 kHz with over 120 dB of alias rejection and lower CPU use.
• macOS 12 or later is now required.

This update is free for all Corona 6.x and 7.x customers.

OPL 3.2

Version 3.2 adds a multi-operator mode with up to four modulators and four carriers per note on a pool of eight OPL3 chips.

• Eight preset algorithms plus Custom, edited on a Yamaha-style algorithm chart.
• Loads WOPL, WOPLX and OPLI banks and TX81Z, DX21, DX27 and DX100 sysex dumps, with over 9,000 new bank instruments.
• Master Volume with output meter, and a Saturator with Valve and Tape voicings.
• Sample-accurate MIDI timing, sustain pedal support and stuck note fixes.

This update is free for all OPL customers.

Retromulator 1.8

Version 1.8 adds an Oberheim Matrix-1000 core.

• The original firmware runs on an emulated Motorola 6809 board driving six CEM3396 voice models, oversampled 2x.
• Banks 2 to 9 load from the patch EPROM, and all 96 patch parameters have a MIDI CC.
• LFO 1 and LFO 2 can sync to the host tempo or incoming MIDI clock.
• The iOS firmware picker accepts several files at once.
