I can't think of a better synth to do bass and leads for a Snarky puppy type situation.
The sub37 is a simple machine, far easier than the little phatty as it's all in front of you ready for tweaking.
If you know subtractive synthesis then it's perfect synth to quickly dial in basses. The only thing you have to really work out is the way the Mod busses work and can be routed. Once you have that then it's plain sailing.
I don't know of any vids or books that can help you, I just spent time with various synths to learn what happens when you turn a knob or move a slider etc. The best way I think.
Out of all my mono synths the sub37 is more instantly a bass/lead synth than any other. It excels at exactly what you want win just with a few tweaks. Alot of synths need alot more tweaking to get good bass but a moog just has it right from the raw osc. Sure, it can go all spacey and make weird noises that will keep many people happy but I don't think that's what the majority of professionals will be using it for, they'll be using it mainly for the moog sound on basses/leads.
This might help you, it might not but it's what I am doing right now because I have no use for the presets.
Go to bank 16 slot 1. All these patches are init/blanks presets and will help you start building simple basses etc. Once you have something, save it and fill up the banks backwards.
Start off with the oscillators. Put osc 1 at 12 oclock. set to 16'. Tweak the osc wave to see what type you want. Sounds bassy, but not enough right? add a sub to whatever level you feel (past 12 oclock it will drive the osc and start taking out the 1st osc) The sub is a square wave, if your 1st osc is set to triangle then the sub will over power it. try setting osc 1 to 8' then lowering theoctave on the keyboard to get lower notes. Then turn up osc 2 and set to triangle as well but at 16' so it's acting as the sub osc. Lets concentrate on a snarky puppy bass though so put you osc's somewhere around the saw, you can tweak later to taste anyway. Now you can start tweaking the filter. Drop it until you feel it's darkened enough. There is no bite though. That's all in the filter envelope. So turn the filter env amt up then move the filter envelope decay up, past 12 oclock you should start to hear the envelope open up and let the filter through right at the start giving a "BOW" sound. If you turn the attack up too you'll get a "WOW" sound. Turning these up more will give you longer BOOOOW'S and WOOOOW's ha. The env amt knob will set how much the filter will open up. The higher up the brighter the start of the note. Snarky won't have any resonance on their basses particularly but do on their leads so experiment with setting some resonance. Be mindful that higher res settings will seemingly lower the volume slightly. Now, you have a "BOW" bass sound. You just need to fine tune those settings to get the timbre and bite you want.
For anything like this, just ignore the mod busses unless you want to use a bit of vibrato like Sean or Cory use on their leads. Use Mod one and just turn the pitch up the tinyest amount so you can just hear a wobble, adjust the speed of the LFO to taste and it should already be set to triangle by default. Don't forget to push the mod wheel up or you won't hear a thing.
It's total bread and butter for any moog synth but I can see why the sub37 can steer you away from these sounds because of the amount of crazy presets it has. It can be overwhelming. The presets are great and showcase the moog but I wouldn't rely on them. They are a brilliant convenience though so I'm not knocking them but having so many does not promote learning the instrument. You can try and deconstruct them to learn, sometimes that works but there is nothing like learning synthesis from start, the raw sound of just one osc and then adding and then subtracting.
Hope that helps and didn't sound too condescending
