Synth 76477 is a powerful sound effects generator and synthesizer app, inspired by the famous SN76477 integrated circuit from the 1970s, but containing many enhancements. Features: • Three oscillators, each of which can produce a sine, triangle, sawtooth, or square wave • The outputs of two of the oscillators can be used to modulate the main oscillator • Frequency modulation can be linear or octave based • The duty cycle of the main oscillator can be adjusted in square wave mode • Noise generator, either analog or digital, with an adjustable low pass filter • Oscillator outputs can be mixed to the audio output • Fully configurable ADSR (Attack / Decay / Sustain / Release) envelope, linear or exponential • One shot mode available • Unlimited number of sound effect generator boards • User configurable array of sound effect generator buttons on each board, up to 50 on the iPhone and 150 on the iPad • Boards as well as individual generators can be exported and imported, and transferred to and from your computer via iTunes file sharing, making it easy to share with others Synth 76477 comes with a full set of sample sound generators, making it easy to understand how to use and configure them, and tap the full power of the app. Synth 76477 works with MIDI input devices (keyboards and controllers) in several interesting ways: If you plug a MIDI device into an iPad (via the USB Camera Connection Kit), Synth 76477 will automatically use it. You can plug several MIDI controllers in via a powered HUB, and Synth 76477 will use all of them. You can also use MIDI controllers over WiFi. Midi controllers can be used to trigger chip playback, or set the VCO frequency and volume. They can also be used in the chip editor to adjust the various settings. The app also supports Bluetooth audio devices.

https://youtu.be/pwx72zQD0p8 Morphix - Morphing Wavetable Synthesizer Morphix is a polyphonic morphing wavetable synth and a faithful reconstruction of the lost 2005 FSR Morphite. Its architecture, parameters, and complete 64-patch factory bank were reverse-engineered from the original and rebuilt from scratch with JUCE — now a modern, multi-platform instrument themed after Aleph Void. A morphing oscillator feeds a state-variable filter, an amp VCA, and a stereo flanger, shaped by independent amplitude and filter ADSRs and a tempo-synced LFO. Sweep the morph parameter for evolving, animated textures — from glassy pads to gritty leads — all wrapped in a clean, dark Aleph Void interface. Features • Morphing wavetable oscillator into a state-variable filter (cutoff / resonance / env / keytrack) • Independent amplitude and filter ADSR envelopes • Tempo-syncable LFO routable to morph and cutoff • Built-in stereo flanger • Full pitch section with bipolar tune / fine • 64 factory presets recovered from the original synth • Import / Export your own .vstpreset patches • Branded Aleph Void UI — void palette, violet accent, JetBrains Mono type • AUv3 plug-in for use in GarageBand, AUM, Logic, and other AUv3 hosts Plays in your favorite DAW or stands alone. Built by Aleph Void. https://morphix.alephvoid.com
