Hi B3 fans!
if is it of interest i can give you my experience with the Wersi Abacus keyboard:
There is a basic XG sound module with 'standard-fixed' sounds ,including organs.
The OX7 is an optional item (which i have installed) and it can produce Hammond B3/H100 and Wersi Organ sounds ,using the 9/7 RealTime Drawbars,complete with KeyClick,Leslie emulation,Scanner Vibrato etc.it The OX7 is based on a Motorola DSP chip,the current software version is 7.6 and it is also user programmable.
On the next level,there are the OAS sounds which use more DSPs and can be loaded with any AKAI compatible sounds ,lots of sampled organs among them.But the beuty of the system is that -as it is based on a Windows PC-any Windows sound generator can be used in real time.I have tried NIB4 and works.I can 'play' the B4 drawbars using the Colour Touch Screen.It is possible to layer all different sound sources on the various keyboard zones.
The new version OAS4 that just came out ,gives full support to Gigasampler,with the possibility of reacalling the Gigasampler sounds using the front panel buttons.I will give you my impressions when i install this.
Have in mind that all sound processing ,including effects and equalizer, is done digitally (32bit) and the 24bit D/A converter is at the output.How it sounds? Maybe I have to post some sounds so you can listen and give your feedback.
