Clocker is a utility plug-in that sends MIDI clock, giving a separate and adjustable clock source alongside the one the host application already provides.

Latency Fixer is a plug-in that reports a latency of its own to the host application, set by its parameters, while applying no processing to the audio signal. The host's own delay compensation then advances the audio fed into the plug-in by the requested amount.

Merger is a utility plug-in that combines two audio channels into one. It is typically useful for plug-ins such as vocoders that expect their two inputs on either side of a stereo pair.

MidiNull is a simple utility plug-in, created in response to a requirement identified in a post on the Ableton forums. It is a VST instrument that passes audio through unchanged and does nothing in response to MIDI.

The NINJAM plug-in is a plug-in client for NINJAM, the online collaborative jamming system. Hosting the client inside a plug-in makes it easy to combine NINJAM with a computer-based music setup and opens up routing options for signals going in and out of it.

Persephone is a Eurorack VCA (Voltage Controlled Amplifier) that uses a discrete JFET as its gain element, which can be gently or heavily overdriven for saturation and distortion effects. It also includes a zero-crossing detector that keeps fast gain changes free of clicks.

The NTX-8CV is a 4HP Eurorack module with three quite distinct purposes: MIDI to CV conversion, eight channels of USB audio class CV or audio output, and expanding a disting NT with eight more CV outputs. Its dual role USB port works both as a class compliant device and as a USB host.

The Select Bus breakout provides access to the MIDI-based Select Bus protocol used by some Expert Sleepers modules and by a handful of modules from other manufacturers. With it, multiple modules can be made to save or recall presets at the same time, remotely controlled over MIDI.

The Tiny MIDI breakout is a 2HP Eurorack panel that carries six passive 3.5mm TRS MIDI sockets that can be shared among compatible modules and wired for Type A or Type B 3.5mm MIDI. It draws no current and connects to the module behind it with a four-way ribbon cable.

The Expert Sleepers USAMO (Universal Sample-Accurate MIDI Output) provides a sample-accurate, jitter-free MIDI output from a DAW. A companion plug-in turns MIDI into audio, and the standalone box reconstructs it on a 5 pin DIN MIDI socket.

Augustus Loop is an emulation of a tape-based delay effect, with extra features that make it usable as a looping device.

Little Spacey is a delay effect inspired by classic analogue bucket brigade delays, with refinements only possible in the digital arena and a maximum delay time that would be very costly to realise in hardware. It works in mono, stereo or multi-channel settings and can modulate its delay time for chorus and vibrato effects.

Meringue is a delay effect whose delay runs alternately forwards and backwards rather than continually forwards, so echoes play in both directions and the gap between a note and its echo varies. A filter and saturation section and a large view of the delay buffer are included.

The ES-8 is a USB 2.0 class-compliant audio interface in a Eurorack module, with DC-coupled inputs and outputs that can carry both CVs and audio. ADAT inputs and outputs and an expansion header for the ES-5 extend the channel count beyond the eight outputs and four inputs on the panel.

Spectral Conquest is an effect plug-in that lets you directly manipulate the frequency spectrum of audio signals. The signal is analysed with an FFT, modified band by band or by script, and then regenerated by an inverse FFT.

Silent Way is a suite of plug-ins designed for use with analogue synthesisers, and especially as part of a modular analogue synthesiser system. The plug-ins make and process no sound of their own, they generate control voltages that can be patched into the control inputs of an analogue system.

Minky Starshine is at heart an additive synthesiser, augmented with possibilities for subtractive synthesis and pulse width modulation. Its waveform is built by summing 16 independently controllable partials, which can be grouped and animated by envelopes and LFOs.

Warbler is a vibrato plug-in from Expert Sleepers whose extra controls reach into chorus, flange and delay territory. The vibrato LFO spans 0Hz to 5kHz, so it covers subtle modulation through to hybrid sounds that are not easily categorised.
