Read full description

3DSynth! A chromatic touch synthesizer and on-device recorder. Chromatic by design - 3DSynth lets you play all notes and frequencies continuously—not locked to MIDI steps—so you control pitch directly with your finger like a real instrument! Real-time, responsive play - Low latency and immediate feedback keep your phrasing natural and expressive while you glide and shape the note in motion. Shape your sound - Choose different instruments (oscillator, FM, plucked), sculpt with ADSR and add effects like reverb, modulation, delay, distortion, and EQ! Record on device - Capture your takes directly to the app’s local recordings folder for sharing and backup. **Important** Deleting the app removes its local data, including recordings and settings. Export anything you want to keep before uninstalling or resetting the device. Enjoy and thanks for downloading!

About

HotMix Listen

Features
Read full description

HotMix turns an iPhone or iPad into a personal monitor mixer for production sound — no belt pack required. It connects to the HotMix Server on your Mac and streams up to 32 live channels over local Wi-Fi. Everyone on the crew mixes their own blend on their own device, so the producer's mix and the boom op's mix can look nothing alike. WHAT YOU CAN DO • Tap a tile to drop a channel into your mix. Long-press for a fader. Taps respond right away — every channel is already streaming, so nothing waits on the network. • Read live captions of what each mic is saying, transcribed on the server. Because each channel is one mic, the speaker labels are exact — no guessing who said what. • Save a mix as a Scene and bring it back with one tap. Handy when you jump between an interview setup and a wide. • Star the channels you care about to pin them to the top, and sort the grid the way you work. • On iPad, Auto tile size goes compact for big casts, so 32 channels still fit on one screen. • On iPhone, captions keep running on the Lock Screen and Dynamic Island while the app is in the background. You decide whether a locked screen shows full dialogue or just the speaker's name. • A jitter buffer, adjustable from 40 to 200 ms, rides out Wi-Fi hiccups, and the app reconnects on its own if the signal drops. There's no login, no account, and nothing leaves your network. HotMix finds the server automatically once you're on the same Wi-Fi. HotMix needs the HotMix Server companion app for macOS and a local Wi-Fi network. Use wired headphones or in-ear monitors for the lowest latency — Bluetooth adds too much delay for monitoring.
