Description

CVOsc
CVOsc turns a DC-coupled USB audio interface into a portable, multichannel oscilloscope for your modular synth rig. Connect an Expert Sleepers ES-9, ES-8, or any class-compliant DC-coupled interface to your Android phone or tablet, and visualize up to sixteen simultaneous channels of Control Voltage and audio — no laptop, no patch cables to a computer.

See your patch

• Up to 16 simultaneous channels in a paged, responsive grid
• Three display modes: All (every channel), Selected (just the channels you tag), and Overlay (selected traces superimposed on a single canvas for phase and correlation work)
• Per-channel range, offset, and time base, in volts for CV and normalized units for audio
• Auto-trigger on zero crossing for rock-steady waveforms
• Auto-fit to waveform when you just want the trace centered
• Independent CV vs Audio mode per channel, with renameable identities ("VCO 1", "LFO Slow", etc.)

Listen in

• Built-in live monitor: route any input channel to any physical output of the interface
• Monitor multiple channels simultaneously, each to its own output
• Output assignments persist across sessions
• Hot-plug aware — disconnect and reconnect, and CVOsc rebinds automatically

Pro features (auto-renewing annual subscriptions, sold via Google Play)

• Tuner — pitch detection that works on both CV pitch signals and audio. See note name and cents offset live in the pane.
• Record & Playback — capture every selected channel to its own WAV file, then play recordings back through the interface. CV recordings are routed only to DC-coupled outputs; the app warns you if you try otherwise. Live monitoring and playback share the same USB pipeline, so you can play recordings while monitoring live channels at the same time.
• Saved Channel Settings — every channel comes back exactly the way you left it on the next launch.
• Presets — save and recall whole-rig configurations: channel names, signal types, all scale settings, monitor routings — under a single name.

Each subscription is independent. Restore Purchases in Settings re-entitles anything you've previously bought on this Google account. Cancel anytime in Google Play; cancellations take effect at the end of the current billing period.

Hardware requirements

CVOsc requires a class-compliant USB audio interface and a USB-C OTG cable. To visualize CV signals (not just audio), the interface must be DC-coupled. Verified hardware includes the Expert Sleepers ES-9 and ES-8. A powered USB hub is recommended for tablets that don't supply enough bus power.

Privacy

Audio captured from your interface is processed on-device only and is never transmitted by CVOsc. Recordings stay in app-private storage unless you enable Android cloud backup in Settings. Anonymous analytics and crash reporting can be disabled in Settings → Privacy at any time, and are off by default for users in the EU/EEA/UK/Switzerland until you opt in.
