Hello Ketron AJ

I am using wave file drum loops in my styles in the drum2. I import my drum loops by using floppy disk and process them in the SD1 sampler. I loop them as well as syncing them while processing them. When I play my styles the drum2 loops change tempo as I change the tempo but thier pitch changes.

I wanted to know if this is normal or not.
SD1 is using live drum loops with most of its own styles but thier pitch doesn't change when you change the tempo.

Thanks in advance

Following your description above, this is normal (with the current OS1.0).
The pitch changes because when the tempo is changed, the time length of the measure changes accordingly. In order to adjust to the time of the wave KETRON stretches/compresses the wave to match the selected tempo value, however, this causes a change in pitch. Tempo changes of patterns with waves are valid only for little variations , where the pitch change is not important.

Yes, the SD1 uses live drum loops and its pitch does not change with tempo variation. This is because:
(1) the files/loops that they use are 'proprietry' wave files that have been custom -developed with their wave-sync technology for the SD1 and not just 'sampled wave loops'.
(2) some of the drums are 'mini-samples' sampled onto keys (live drums). These notes are called as programmed (just as in drum1) and the samples assigned to them are produced. So, when you change the tempo, you are not changing the actual sample, just the rate at which the notes are 'called' to produce their associated samples. I hope I've not confussed you here!

I would suggest:
* Set the tempo of the style you would want to sample to first while in PATTERN EDIT mode. Also count the # of measures!
* Process the sampled loops as you do now - use the current number of measures of the style in the Sampler. You should see the tempo value change to match that of the style - if not, close enough. Sometimes you might have to use the TEMPO [Slow/Fast] buttons to adjust/change this tempo value as the SD1's value isn't ALWAYS the best.

Hope this helps!

Thanks,

AJ

Helle Ketron AJ,

Thanks for your response. Do you know if they will fix this problem with the upcoming O.S
upgrades? Also there is one more thing I forgot to mention to you and that is the delay in fill ins. I happen to use live drum loops with all my custom styles and there is a serious delay with the fills.

If you try most of the built in styles that use live loops in drum2 you will feel the delay in the fill ins. I just happen to see and try the X1 keyboard in a music store, and I didn't experience any delay in the fill ins as I am experiencing with my SD1.

Do you know if this has to do with the software, perhaps they should free up some memory for this transition.

Thanks again for your help.

Sev01,
Below are responses to your Qns.

Do you know if they will fix this problem with the upcoming O.S
>>AJ: I don't have any information at this time to support this. Based upon the design of the GROOVES/Drum2 and how they are implemented, I don't think it will mearly be an easy software fix. To avoid most of this problem though, do the following:
* From the default screen, press ARRANGER MODE (F3).
* Go to PAGE 2 and press F2 to DISABLE the AUTOCRASH feature. The delays in the FILLS should now be less noticeable.


Do you know if this has to do with the software, perhaps they should free up some memory for this transition.
>>AJ: I don't believe this has to do with memory ... rather with quantization. Again if you were to go ahead and quantize 'grooves' then this will defeat the prupose of having live drums ... they will no longer be grooves as they would LOOSE their 'humanized' aspect/touch.
Normally, you us FILL1 to go from ArrA->ArrB, FILL2 B->C, FILL3 C->D. A quick-fix for Ketron/users would be:
* in FILL1, use the same groove/drum2 arrangemebt from Arr B
* in FILL2, use the same groove/drum2 arrangement from Arr C ...
But you see, this will NOT work then if you are in ARR B, use FILL1 and then go to ARRD. Again, this isn't an easy fix, but try my suggestion above with the AUTOCRASH and let me know.

Thanks

AJ

Ketron AJ,

I tried what you suggested about the auto- crash. I think when you turn the autocrash off the fill in becomes smooth all together, which means there is no more delay. Maybe the presence of autocrash slows down this transition. By the way a fill in is no fill in without a crash at the end, it just doesn't sound good. So I think turning off the autocrash is not the ultimate solution.

Thanks and I hope they could fixed this, because it is very annoying.

Hi guys!
Fill delays is something I noticed as soon as I got my SD1.
It’s true that Autocrash causes this delays , but not in all styles. The problem occurs when that ‘’standalone’’ crash (cymbal) sound is not in the current drum set. At the moment the crash is supposed to play, a program change has to happen to pick it up from some other drumset and this unavoidably causes the delay. In my opinion the SD1 will have to be programmed in the way, that for each style the Autocrash sound will reside in the drumset currently playing.
I’m 100% sure Ketron engineers will fix this problem, hopefully in the coming release. Those delays disturb the music and just have to disappear.
Anyway, this Saturday I will have my first gig with SD1 and a first gig after a long time. I hope I will manage it!
