HG Fortune Percumat 2
Platform/format: PC/VST Download
As its name suggests, this is a percussion machine rather than a straight drum one. You can use up to six instruments at a time, and there are 512 built-in sounds. Beats can be constructed in the two supplied step sequencers, which offer a number of special features that enable you to create more experimental patterns.

LePou LeGion
Platform/format: PC/VST Download
This latest addition to LePou's collection of guitarist-friendly plug-ins is a high-gain preamp. It's not based on any specific hardware model, but the developer says that his aim was to "build a high-gain amp sim that doesn't need any booster in front in order to be tight". There are two channels, each of which has rhythm and lead modes.

Iliadis iSpinner

This is another emulation of the classic Leslie rotary speaker, but with what the developer describes as "some differences". You get rotary chorus and adjustable overdrive, while the speed, depth and spread of the rotator itself are all tweakable too.

This revised version of the parallel multi-filter plug-in adds three new filter types (low-pass, high-pass and notch join the already-present band-pass) and stereo balancing on each of the four filters' outputs. You'll also find four LFOs that are host-syncable.

Platform/format: PC/VST Download
Yamaha's CS-01 was an entry-level monosynth that was released in 1982 (a mark II version arrived in 1984). This is an attempt at a software emulation, with version 2 promising to deliver a smoother GUI, an animated keyboard and improved stability.

Voxengo Span 2.0
Platform/format: PC, Mac/VST, AU Download
This real-time "fast Fourier transform" audio spectrum analyser is now cross-platform and has added multi-channel and mid/side analysis to its roster of features. A few 'housekeeping' tasks have also been taken care of: undo/redo is now in place, and some tweaks have been made to the interface.

rs-met CrossOver
Platform/format: PC/VST Download
This VST effect plug-in is designed to split an incoming audio signal into up to four frequency ranges so that you can then build your own multiband effects (or, using two bands, create bass effects). It does its work using low-pass/high-pass filters, with the slope being adjustable between 12 and 96 dB/oct.
