Adam,
Thank you for the follow up to my post.
Yes this machine is a beast and im super intimidated with it! With the mod martrix and menu diving for all of the other features, it gets intimidating.
Me personally, im appreciative of these types of videos and I again thank you for taking time to do this. Very simple to understand.
Fun story: i was at namm this year in LA and stopped by to see Mr. Linn at his booth. I asked him to show me how to make a kick and to see him whip one up within a couple of minutes all whilst explaining what he was doing was fascinating to see. That little demo really opened up. My eyes and put things in perspective. He's such a master at this.
Look forward to the snare video!! ;-) just saying...
Adam, thx for this. How did you know the paremeneters? Just trial and error?
And yes if you can do a 808 snare that would be choice.
I really appreciate tutorials like these because it helps me to understand how to use the tempest as Im very intimidated with it.
Yorg's 808 sample pack is really nice as well, however its great to see how the sausage is made if you will... 
Basically what I did was have my Roland 808 sample loaded up and kept referencing it while designing the sound on the Tempest. Getting the Amp Env settings was actually the trickiest part, and I got pretty nerdy with it by recording the Tempest output and then comparing it to the original 808 sound to make the curves close as possible (comparing the relative volumes after 100ms, 200ms, etc.) While that might seem like overkill, part of the "oomph" and character of the 808 kick is how that volume curve looks.
Glad you liked it. I've got the 808 Snare already made (the Tempest can actually get surprisingly close with it), I just need to do the actual video. Part of why I wanted to do this was because I think the Tempest is a very intimidating instrument to those unfamiliar with drum synthesis and learning how to make the sounds yourself is half the battle (and half the fun!).
