We have searched on all the web for free VST emulation of the Arp 2600 synth :
unfortunately, there’s really only one. The good news is that it’s a very good emu!
**edit **: une fois n’est pas coutume we have not searched deep enough ! Thanks to BlackWinny (see the first comments), another Arp 2600 like emu is available for the masses!
Come on let’s do it :
1. Arppe2600va by Glen Stegner
Arp 2600 VA VST

Based on the Richard brooks Synthedit source, the Arppe2600va is a must have, for all semi modular virtual analog lovers. Despite some bugs it has all you need : three oscillators, an ADSR generator, a LFO, a Sample & Hold Unit, a Filter, a spring reverb and many more!
If you are not familiar with the Arp 2600 you may have a look at the manual before programming some patches :

This (free!) eBook by Samuel Ecoff is also a must :

The matrix on the Arppe2600va VST is less fun that “patch chord” but is very powerful and easy to use.
