Repro vs Thorn

Repro is a synthesizer plug-in containing Repro-1 and Repro-5 in one product and installer. Repro-1 models a monophonic analogue keyboard and can step-record two patterns of up to 32 notes each. Its five rearrangeable effects include a wavefolder, delay, EQ/resonator, reverb and sonic conditioner. Repro-5 supports up to eight-voice polyphony or unison, with optional glide, and includes more than 950 factory presets and a polyphonic distortion unit with four modes, including a bit crusher. The product runs on Linux, macOS and Windows, but is not standalone and requires host software; it supports nearly all DAWs. The listed plug-in formats include CLAP, AUv2, VST3 and AAX on macOS, and VST3, CLAP and AAX on Windows. Repro is NKS-ready and compatible with Maschine and Komplete Kontrol hardware. The listed Repro plan costs €149 as a one-time purchase, and a free trial is available; its demo emits a crackling sound. Linux builds are beta and receive less support than macOS and Windows versions.

Thorn is a software synthesizer for modern electronic music production, available as a 64-bit plugin for Windows and macOS. Its three spectral oscillators shape harmonics and support FM, ring modulation, pulse-width modulation and hard sync. Sixteen-frame spectrum tables provide editable, morphable harmonic sources, while additive spectral synthesis, harmonic filtering and spectral effects form the sound engine. Two analog-modeled multimode filters and nine effects extend sound shaping. Modulation includes three ADSR envelopes, three LFOs and two multistage envelopes. A flexible 16-step arpeggiator outputs MIDI, and a grid-based Glitch sequencer supplies another sequencing method. Plugin Alliance lists more than 600 presets. Thorn runs in VST2, VST3, AU or AAX hosts and is not a standalone application. Listed operating-system support is Windows 10–11 and macOS 13–26, including Intel and Apple Silicon Macs. A 14-day trial is offered; earlier-license owners are quoted a $19 USD upgrade.
