The older computers also ran around 1 to 4 megahertz (MHz), whereas the Raspberry Pi runs at 700 MHz. And the Raspberry Pi is far from the average home PC. Today, boxes with 2 GB RAM and 2 GHz processor speed are common.
ASIO is a standardized way of describing the communication between audio software and a piece of audio hardware. It enables audio hardware manufacturers to write optimized drivers for their hardware that bypass the potentially high latency operating system mechanism for supporting audio hardware.
Solution found!! After combing through the internet for days, here's a workaround that I found. Apparently the main problem is that GS Wavetable Synth and the ASIO driver use the same port, but settings are set so that only one can use it at a time (exclusivity). You need to change this in control panel.
