LogSynth vs SL Bass

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 — 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 — no watered-down mobile version, no feature gating between standalone and plugin modes.

SL Bass is a bass synth and 808 instrument for iPhone and iPad. Explore 146 factory presets and 102 bundled sample variants, then shape each sound with editable pitch and amplitude envelopes, mono and legato modes, glide, saturation and a playable keyboard. Use SL Bass as a standalone instrument or load it as an AUv3 in a compatible host such as GarageBand, Logic Pro for iPad, AUM or Cubasis. The interface adapts to compact iPhone and iPad windows while preserving direct touch control. Features: - 146 factory presets - 102 sample variants - Editable pitch and amplitude envelopes - Mono, legato and glide controls - Saturation and output control - Standalone app and AUv3 instrument - Local processing with no account or subscription SL Bass is an instrument and responds to MIDI notes. It does not process incoming audio as an effect. Support: support@sfoorlabs.com
