shouldn't you really have loaded in the same samples? i know you'd have to have converted the wave to 40kHz 12 Bit for the 60, but seeing as that's what the 60 is doing anyway, it should n't matter, right? what are youre thoughts?

hmm.. i think converting the wave on the pc could give markedly different results to using the builtin convertors at their native sample rate.

I was thinking more to suggest finding a 3rd set of D/A convertors (a good 'neutral' one) and go from the pc thru that to both machines.

I think it is fair and relevant to test the input convertors (since its part of the beast's flavor) but it should be tested on both.

and i don't know why but the idea of going thru one to the other makes things seem a little biased.

anyway, again thanks for the effort and that sh*** is fun to hear.

yeah i agree. a possible solution: you could get a 24bit 96kHz sample or samplkes, and convert them with something like wavelab to their required sample rates, so both would have the same 'colour' from the pc conversion. well, as near as dammit.

no doubt. I can run from my G5/Peak then out of my apogee into the mpc's. I'll need to really nail the levels since hitting the mpc converters differently really effects the dynamics. This particular 60 really seems to distort easily. I have the mixer level on the output more than 3/4 on the 2500 and it's still hot.

The purpose of this post was to determine if the legendary swing of the 60 is replicated by any of the non Roger Linn machines, specifically the 2500.

Is there a difference in the feel that would require you to add a 60 to your arsenal?

I might need to to pick up a usb floppy drive to make this happen. I made a beat last night on the 60 and this morning the machine told me the disk was bad. Gotta love vintage machines :wink:

good points.

but i for sure hear a timing differance.

someone who hears a timing difference, could u please describe what u think it is, so i can listen for it?

i get to distracted by the difference in sound quality to hear a timing difference...

people are just listening the groove. Either you can hear it or you can't :wink:

kinda like what makes your head bob

like its feeling

well i hear a big difference in frequencies and it makes my head bob differently...

im not convinced u are hearing anything other than that :twisted:


... i would think a really tight professional drummer could listen to it and tell me if the 8th notes were swung a little more, or if the snare was coming in later, or what...

Since the point of this is to tell the difference between the groove, if any, why not remove all issues of sonic quality of the samplers and use both devices as midi sequencers only and have them trigger the same external sound module?

Then we will have identical sounds and can listen for the timing.

now that's a good idea. then you could put the wav files alongside one another in wavelab or something, and see how tight they are.

Yeah I agree too that sounds smart... make sure to use a module with tight midi response.

It was also interesting to hear the different sound quality thought, that's for sure.
