I'm too lazy to build a sound.
I have a Yamaha DX-27S which, according to the manual, has the ability to allow users to "build their own" sounds....and 127 memory locations in which to save them..... I tried it once.... I'm not a sound programmer.
not enough time for me to set around and create a new sound from scratch..... I'll use the preset sounds....and if that's not good enough....one of the Komplete synths (I forget which one) has the ability to alter the original patch with knobs and other gizmos..... more then sufficient to keep me entertained for hours.
For you guys who do find that fascinating.... my hat is off to ya.
That's my 2 cents on it.....
