OB-Xd 3.20 released
OB-Xd is a classic virtual analog synthesizer that recreates the Oberheim OB-X with enhancements like micro random detuning, polyphonic unison, and bi-directional MIDI control.
Version 3.20 introduces a fully independent second LFO, MPE support, a reworked MIDI Learn workflow, and a new Knob LED Visualizer system that brings real-time visual feedback to the entire interface.
What's New
- Second LFO (LFO2): A fully independent second LFO runs in parallel with LFO1, with its own rate, three waveforms, two amount controls, five destinations, and tempo sync. The single LFO panel switches between LFO1 and LFO2 via a dedicated edit switch, with a separate sync button toggling tempo-sync per LFO (or both at once when shift-clicked). Old presets load with LFO2 silent.
- MPE Support: Full MPE compatibility with configurable per-axis routing for pitch bend, aftertouch (pressure), and timbre (CC74). Each axis has its own depth control, polarity, and destination. Y-axis rest toggle returns timbre to neutral on note-off. MPE configuration caches in MIDI.xml so new plugin instances inherit your last-used setup.
- Reworked MIDI Learn: New state-machine workflow with live LCD feedback ("MOVE KNOB", "WAITING FOR CC", "CC SET") and the LEARN button blinking in time with the prompt. Reliable touch detection driven by a mouse listener so preset loads and host automation can no longer falsely trigger learn. LFO2 controls are fully MIDI-learnable, including dual-view retargeting.
- MIDI Board Management: Save As, Rename, Delete, Import, and Export your custom MIDI CC mapping boards directly from the MIDI menu. Boards auto-grouped by manufacturer with a separator after Custom entries. Unified mapping engine driven entirely from MIDI.xml. Includes new and revised MIDI boards out of the box.
- Knob LED Visualizer System: Real-time visual feedback across the interface, including Volume VU meter (-90 dB to 0 dB), live filter cutoff envelope and LFO modulation tracking, animated Amp and Filter ADSR strips during playback, LFO modulation preview on Osc1/2 pitch and Pulse Width knobs, velocity-to-amp and filter envelope source/amount previews, per-voice pan activity, bipolar LED mode, and LFO routing buttons that flash on toggle while waveform buttons pulse in time with the LFO.
- Persistent Voicing: New option in the Programs menu preserves voice count, unison, and multiply-voice settings across preset and program changes. Settings are saved in settings.xml so your performance setup survives sessions.
- Preset Bar Workflow Improvements: Anchored Disk Browser popup on Bank LCD click, native New Preset / Rename / Save dialogs (with Shift-click bypass), Rename Bank action and Shift+click bank shortcuts, search field added to the bank popup, Shift / right-click navigation shortcuts on prev/next buttons to jump by bank or folder, and slot cycling on the bank LCD.
- Standalone MIDI Out via Virtual CoreMIDI Port: Standalone build exposes a virtual CoreMIDI port for MIDI Out, replacing the prior virtual port input. The MIDI Out selector is now forced visible in Standalone for routing to external gear or other apps.
This update is free for all OB-Xd 3.x customers. OB-Xd is available for Windows, macOS, and Linux in VST, VST3, AU, AAX, LV2, and Standalone formats, and Standalone and AUv3 for iOS.
