Bell Sound Synth
The default way of starting out to make a bell would be FM or ringmod. However, to make a GOOD bell sound..thats a little more than tuning in ringmod and hoping something happens. With FM it gets really complicated because all sorts of variables can enter in to play, such as how "metallic" or "complex" you want the transient of the bell to sound, etc. However, I can give you a simple analog bell patch here,
Mix two pulse or triangle waves (say OSC 1 and OSC 2), with OSC 1 ringmodding OSC 2. Tune OSC 2 to an octave or 2 octaves above OSC 1 to make the bells "tine" sound. Now detune OSC 2 to taste, with more detuning making a more metallic sound. Finally mix the two OSCs to taste, add a LPF at around 50%, and put a slow LFO to both pitch and volume. The amp envelope settings should be somewhat obvious, the filter's env settings can be messed around with depending on what you are going for.
This will give you a good "tine" and some vibrato and tremelo which good bell patches have (IMO). With FM it gets really complicated; I'm still learning myself, but the same idea applies as above, just substitute ringmod for FM. Things get more complex from there on, but that should be a good starting place.
