Just sharing some photographs of internals for the Orla Compact Theatre in case it helps anyone (or for the curious)...

Another thing I found of interest are the two sound generator boards (arranged as Master and Slave) which are based on Dream SAM9708 wavetable chip and each board has 64MB of flash memory with small amount of working RAM. I would be interested to compare and see how much ROM and what DSP is used in GT9000 and earlier models. With the two SAM9708 chips, I would guess the organ has a maximum polyphony of 256...
