Larigot, the Roland A37 floats my boat. I have used it for years and use it every day with my software based arranger system which includes the NI B4. To make all this work as it should, I also use the Roland PK5 Midi Bass Pedals. I split the A37 and I have a very good sounding responsive Hammond B3 Organ. Oh and I also use the Yamaha volume pedal for additional expressive control. While it is not perfect, it is close enough. Plus I can carry all of it including the computer under one arm!!!
