jcazzy Posted October 31, 2013 Share Posted October 31, 2013 Probably been covered before but did a search on this and didn't come up with anything. Is there a standard for the slow/fast speeds of a 122 Leslie? One of the things that I have tweaked on my Hammond XK-1c is slowing the default fast speeds down on the on-board sim. I know that all that matters is what I hear (right or wrong), but would like to know if there was a spec for that originally. By the way, the on-board sim does sound pretty darn good. Don't know if it will replace my Vent yet 'cause I've not had a chance to A/B them but I like what I hear so far. John Cassetty "there is no dark side of the moon, really.

mate stubb Posted October 31, 2013 Share Posted October 31, 2013 Well, yes - the standard is a real leslie. There are 3 pulleys on the horn though, so there are really 3 standard speeds. I don't know what they are off the top of my head.

Joe Muscara Posted October 31, 2013 Share Posted October 31, 2013 Don't most sims give you options like 0 - 100 or 0 - 127, or do they actually allow you to use the values in RPM or Hz?

jcazzy Posted October 31, 2013 Author Share Posted October 31, 2013 http://www.dairiki.org/HammondWiki/LeslieRotationSpeed Thanks Jim. The default for the slow speed for both was 36/36. I increased both to 48/48 which improved the slow speed animation. The strange thing is that the default setting for fast speeds was horn/396 and bass/423. I slowed the horn to 381 and the bass to 375. Again, this is subjective and how one perceives the sound. I did think that the lower rotor spinning faster than the horn was a bit out of whack though.

Aussie_Chicago Posted October 31, 2013 Share Posted October 31, 2013 I don't think there is any one definite answer to speeds, due to variables in age and wear of the O rings, the tension of the sleeve that touches the O rings, and wear of belts. Also ramp up and ramp down time can be variable , as every leslie can be slightly different. I had the sim on my Sk2 adjusted what I though was perfect for me, but using it a gig , sounded like the bass rotor was too loud, took too long to ramp up, and I also adjusted the mics to be further away and further spread. The next gig will be the perfect time to hear it all for yourself.

Since I'm listening to my changes through headphones, I'm sure the live sound will be a bit different. And of course, that will change at every venue I play. I'll find a setting I like and just go from there. Thanks foe the input. John Cassetty "there is no dark side of the moon, really.

WesG Posted November 3, 2013 Share Posted November 3, 2013 Fwiw - 48 rpm is definetly too fast for chorale for either motor. Should be more like 38. Big thing to remember is that both rotors are not synchronized so you need different values top an bottom. It's also worth remembering that the lower rotor does not have an adjustable pulley; only the horns do.

Ross Ward Posted November 3, 2013 Share Posted November 3, 2013 Is this something that can be adjusted on a real Leslie? I have a 122A and I've noticed that the ramp time on the vintage boxes seems to be a little faster than mine. Link to comment Share on other sites More sharing options...
mate stubb Posted November 3, 2013 Share Posted November 3, 2013 Belt tension is the primary way of controlling ramp time.

WesG Posted November 5, 2013 Share Posted November 5, 2013 The Leslie 122A motors may have different characteristics than the than the traditional fast motors, so this might not apply, but one thing that seems counter-intuitive is that too much tension can actually make your ramp time slower. A little bit of belt slip helps the motor get up to speed, and then the belt brings the rotor up to speed, kind of like a clutch in a car. Does the 122A have the same delayed switching response as the old 122, or does it switch more like a 147/760/etc?

mate stubb Posted November 5, 2013 Share Posted November 5, 2013 Both my Speakeasy leslies came with a stretchy rubber belt on the top horn, with no idler pulley. The ramp time was way too fast, so I replaced that with the traditional non stretchy leslie belt and stock idler wheel. I further slowed it down by lowering the tension on the idler wheel (changing where the coil spring end was pegged.)

WesG Posted November 5, 2013 Share Posted November 5, 2013 That fella from Pink Floyd actually put weights on his horns so they would accelerate more like a drum. I'm not quite sure where my thinking on ramp speed is yet, I just adjust my motors like the book says and have always been happy.... except I often find myself annoyed at the high end of the lower rotor really going "whu whu whu whuwhuwhu" when I flick speeds on a held chord in certain ranges. This is unreinforced, so it's not my miking. On the flip side, I heard the same damn thing out of a Neo Ventillator, too. So maybe it's just me.

B3Nut Posted November 5, 2013 Share Posted November 5, 2013 A 122A has some delay like a standard 122. The switching is the same, only the motor control after it is different. IIRC fast speed can be adjusted, but no adjustment for chorale. Been awhile since I was last in the back of one. --- Todd A.
