Mono Blue is a very simple mono synth that is ideal for basses and leads.
It has two oscillators, a multi band filter with envelope controls, amp envelope controls, a filter cutoff modulator with various modulation types and built in delay.
This synth was built using the free version of Synthmaker that comes with Computer Music Magazine with the sole purpose of having something light on resources and straight forward to use. I was fed up loading a cpu guzzling monster just to use it for a simple sine bass part.
There is only a 32 bit windows version available and to be honest probably will never be taken any further than it is now.
