discoDSP updates OB-Xd Virtual Analog Synthesizer to v3.22 and Bliss Sampler to v3.14

discoDSP has updated OB-Xd to v3.22, bringing expressive aftertouch to ordinary keyboards with multi-destination routing, invertable response, and a new Poly AT mode for per-finger controllers. The update also fixes Windows HiDPI knob rendering and popup menu scaling.

OB-Xd is a classic virtual analog synthesizer that recreates the Oberheim OB-X with enhancements such as micro random detuning, polyphonic unison, and bi-directional MIDI control. Version 3.22 adds aftertouch and Poly AT support for non-MPE keyboards, so any keyboard with channel pressure can drive expressive timbral changes without needing an MPE controller.

Changes in OB-Xd 3.22

Aftertouch for Non-MPE Keyboards

• Channel pressure can drive any combination of Cutoff, Pulse Width, PW Offset (Osc2), Cross Modulation, Osc2 Detune, Pitch, Pan, and Amp simultaneously, the same destination set as MPE Y/Z.
• Depth and Mod Wheel Scaled controls let you set how far pressure pushes each destination, and optionally ride the amount from the mod wheel.
• Invert flips the response so pressure ducks the destination instead of boosting it - close the filter, pull pitch down, or duck amplitude as you press harder.
• Reads both mono channel pressure and polyphonic aftertouch - poly drives per-voice, mono fans out to all voices.
• Live LED previews on every routed destination so you see exactly what your pressure is doing.
• The Aftertouch menu appears only when MPE is off, so the two never conflict.

Poly AT Mode

• Controllers like the ROLI Lightpad in Multi Channel mode, which send per-finger MIDI channel but no MPE handshake, now drive per-voice aftertouch.
• Channel pressure is re-routed to the last note played on that channel.
• Mutually exclusive with MPE - enabling Poly AT disables MPE and vice versa.
• Notes on any channel are accepted, with per-channel bend collapsing to the global wheel.
• The Poly AT setting is saved per-instance and globally, so new instances inherit your last-used choice.

Windows Fixes

• Knobs no longer render blank at 150% / 200% display scaling - tall high-resolution filmstrips are now sliced past the Direct2D size limit.
• Popup menu text no longer double-scales on high-DPI Windows displays.

Bliss 3.14

discoDSP has also updated Bliss to v3.14, a consolidated release covering five updates over the past month. Highlights include full MPE support, automatic loop cue extraction, tracker module and Jeskola Buzz sample import, four new sample effects, and a significant set of Sample Editor improvements.

Bliss is a professional sampler with VST/AU and hardware instrument recording capabilities, Visual Key Mapper, built-in wave editor, and comprehensive format support including AKAI S1000/S3000/S5000/S6000, NKI, EXS, SFZ, SoundFont 2, and CD-ROM disk images.

Changes in Bliss 3.14

Full MPE Support

• Per-voice X/Y/Z expression with per-channel pitch bend, timbre, and pressure routed independently to each note - works with ROLI, LinnStrument, Osmose, and other MPE controllers.
• Dedicated MPE panel with six routing slots (X/Y/Z) assignable to any modulation destination, each with an amount knob and invert.
• Configurable MPE settings: enable, Poly Aftertouch, timbre CC (default 74), pitch bend range, and per-axis rest position.
• Automatic MPE configuration via RPN, so most controllers enable MPE and set the bend range on connection.
• MPE preset system with save, load, copy, paste, and reset, plus a Paste > Program to Bank option.
• Live preview shows incoming MPE expression depth on the destination knobs.
• Manager-channel pitch bend and pressure are routed as global so hybrid controllers behave correctly.

Tracker and Buzz Sample Import

• Native import of classic tracker module sample formats (.mod, .xm, .s3m, .it).
• Native import of Jeskola Buzz wavetable samples (.bmx).
• Access decades of demoscene and tracker sound libraries directly inside Bliss.

Automatic Loop Cue Extraction

• Analyzes beats, harmony, and timbre to place cue markers around repeating loop segments automatically.
• Turn any loop into a properly cued, ready-to-play sample with one click.

New Sample Effects

• Sin Drive and Tanh Drive add musical saturation and warmth.
• Spectral Mirror provides real pivot-based spectral inversion.
• Erosion Clip delivers gain-compensated stackable clipping for aggressive textures.

Sample Editor Multi-Zone Operations

• Cmd/Shift+click and drag multi-selection in the zone list.
• Multi-zone support for Export, Resample, Time Stretch, Render Pitch Shift, and Trim by Loop Points.
• Double-click on the Sample Editor divider auto-fits zone list width.
• Adjust Root Note detects and sets zone root note from waveform.

Sample Editor Workflow

• Go to Zone submenu for quick zone selection.
• Virtual Keyboard Root Note menu to view and shift the on-screen keyboard octave.
• Toggle to show or hide the Sample Editor zone list with a keyboard shortcut.
• Auto-Adjust Zone List Width option that fits the list to the widest zone name.
• Change Zone by MIDI Note menu item.

Forward-Compatible Modulation

• Modulation-destination serialization is now enum-growth-safe, so patches saved today keep working as new modulation destinations are added in future updates.

Bug Fixes

• Fixed sample editor selection being ignored after a second selection.
• Fixed knob changes not applying to Shift+click and drag-selected zones.
• Fixed lost active zone when reopening Sample Editor.
• Fixed Sample Editor keyboard focus loss and modifier-key note triggers.
• Fixed playback cursor advancing past the cue stop boundary in pitch shift mode.
• Fixed section header preset dropdown arrow not showing on narrow buttons.
• Fixed VST audio silenced after Reset Program when Delay or Reverb on.
• Fixed Windows VST audio build issue.
• Fixed compiler warnings across parameters, GUI, and sample editor.
