The effects are the weakest point of this synthesizer, very bad. If you use some combinations the sound distorts all over the place, it has no 'PAN' either of the waves or of the two layers, everything sounds mono, except for the delay that barely manages to give some depth to the sound. The wave menu is very poor in quantity and the use of the 'marketing' that says 14.000 is pure lie, they are 80+ and nothing more, there you stay. Some short bass sounds can be achieved and they sound very analog, but nothing more than that. The most I would pay for this Synthesizer would be no more than $19.00 but with a value of $69 it is very expensive and does not measure up, maybe if it came with 500 waves instead of 88, maybe....
