discoDSP has announced updates to the OB-Xd virtual analog synthesizer and the FX Bundle effects collection, along with the release of KeyPad, a new MIDI controller app for iOS.
OB-Xd 3.17
OB-Xd is a classic virtual analog synthesizer that recreates the Oberheim OB-X with enhancements like analog mode, micro random detuning, polyphonic unison, and bi-directional MIDI control.
Version 3.17 improves the user experience with informative parameter tooltips and resolves a disk mode preset persistence issue.
What’s New:
- Filter Cutoff Tooltip: Added filter cutoff frequency tooltip with accurate DSP mapping, providing real-time frequency feedback while adjusting the filter.
- ADSR Tooltips: Improved ADSR tooltip format to musical/pro style with proper unit spacing for faster sound design workflow.
- Volume Tooltip: Added Volume tooltip with dB display and improved precision for all dB values.
- Fixed Disk Mode Preset Persistence: Resolved issue where modified preset parameters were resetting to defaults when closing and reopening the GUI window in disk mode.
FX Bundle 3.3
The FX Bundle receives a major Scope update with new visualization modes, GPU-accelerated rendering, and enhanced display capabilities.
Scope 2.3:
- Flurry Particle Visualization Mode: All-new audio-reactive particle system with procedurally generated smoke textures and dynamic star trails, creating captivating visual displays that respond to your music in real time. Switch between Linear, Circular, and Flurry modes for diverse visualization styles.
- Vibrant Rainbow Color Scheme: New Rainbow color mode with smooth, randomized color transitions that fade between random hues, creating dynamic and engaging visualizations with consistently bright, vivid colors.
- GPU-Accelerated Spline Rendering: Ultra-smooth waveform display using hardware-accelerated Catmull-Rom spline interpolation, providing superior visual quality with elegant curves in both linear and circular modes.
- Automatable View Mode Parameter: View Mode is now exposed as a fully automatable parameter, enabling DAW timeline-synchronized switching between Linear, Circular, and Flurry modes.
- Adaptive Config Menu Scaling: Doubles size on large displays (900px+ wide) with proper Retina rendering, ensuring crisp, readable controls on high-resolution monitors.
- UI Refinements: Zoom slider auto-hiding below 150px window height, refined standalone audio settings, and contextual mode icons replacing text labels for a cleaner interface.
Scope is also available on the Apple App Store as AUv3 and Standalone.
KeyPad for iOS
KeyPad is a new MIDI controller app that transforms your iPad or iPhone into a professional touch-optimized performance tool with piano keyboard, drum pads, and XY controls.
KeyPad brings complete MIDI control to iOS with an intuitive, touch-first interface designed for mobile music production and live performance. Use as a standalone app or load as an AUv3 plugin in your favorite iOS DAW.
Key Features:
- Built-In Sound Engine: Play sounds directly without any external app. Supports SF2 SoundFonts, SFZ instruments, WAV, and M4A samples with automatic keyboard mapping and cross-session persistence.
- 2-Octave Piano Keyboard: Responsive touch control with height-based velocity and three curve options (Linear, Exponential, Logarithmic) for natural, expressive playing.
- 9-Pad Drum Grid: Finger drumming surface for creating rhythm patterns and triggering samples.
- XY Performance Pad: Control two parameters simultaneously with multi-touch gestures. Assign any MIDI CC to X and Y axes for filter sweeps, effect morphing, or live sound manipulation.
- Mac Connectivity: Control Logic Pro, Ableton Live, or any Mac music software wirelessly via Network MIDI or wired via USB for zero-latency performance.
- AUv3 Plugin: Load directly inside GarageBand, AUM, Cubasis, BeatMaker, Drambo, or any AUv3-compatible host with full project recall.
- OSC Output: Send MIDI data as Open Sound Control messages to networked applications including Ableton Live, Max/MSP, or TouchDesigner.
- Adaptive Interface: Automatically adapts to device orientation and size with full layout on iPad and compact keyboard-only mode on iPhone.
KeyPad is available on the App Store for iPad and iPhone.
