About

Digitron Synthesizer

Read full description

Digitron is a virtual analog monophonic synthesizer inspired by Korg Monotron and Moog Mavis, but more powerful. It has 16 step sequencer with pattern chaining and sync with Pocket Operator. With patchbay you can connect any module output to any module input, feel free for experiments. Features: two oscillators with four different waveforms(SQUARE, SAW, SINE, TRIANGLE) with octave and detune control two-channel mixer with voltage control low pass filter with resonance ADSR and AR envelope generators two LFOs ( can be used as oscillators) two VCA as well as, a noise generator, sample and hold module, and quantizer the virtual oscilloscope shows generated sound waveforms 16-step sequencer with pattern chaining and Pocket Operator synchronization Midi keyboard support Be free to suggest new features by email or comments.

About

LogSynth

Features
Read full description

LogSynth is a polyphonic virtual-analog synthesizer built for people who care what's actually happening in the signal path, not just what the preset browser looks like. Every voice runs five anti-aliased oscillators (sine, triangle, saw, pulse with PWM, and a band-limited impulse train) plus a dedicated sub-oscillator and noise source, mixed per-voice with independent amp envelopes. Chunky oscillators, crisp effects and a zero-delay-feedback state-variable filter โ€” switchable low/high/bandpass. The drive effect is powered by a physically modeled diode circuit, numerically integrated rather than a lookup-table approximation, so pushing it into saturation behaves the way an actual analog drive would. FEATURES - 8-voice polyphony, 5 oscillators + sub + noise per voice - Zero-delay-feedback state-variable filter with resonant feedback and diode drive saturation - 5 independent oscillator envelopes plus a dedicated filter envelope - 2 assignable LFOs and an 8-slot modulation matrix - Built-in chorus, delay, FDN reverb, and 4-mode distortion - 41 factory presets across Bass, Lead, Pluck, and Effects - One-tap patch randomizer with adjustable intensity - Real-time oscilloscope, on-screen keyboard, and CoreMIDI input - Runs standalone or as an AUv3 instrument inside AU hosts Whether you're sound designing from scratch or dropping it into a DAW as a plugin, Logsynth gives you the same engine everywhere โ€” no watered-down mobile version, no feature gating between standalone and plugin modes.

Verdict

The call

The clearest difference is price: Digitron Synthesizer at Free against LogSynth's $14.99. Digitron Synthesizer also leads on update cadence (daily vs every 4 days) and iOS requirement (16.0 vs 18.0). LogSynth's advantage is in-app purchases (none vs 3). On ads and device support there is nothing between them.
