CMI IIX sampling

CMI IIX sampling

2010-02-15 by WT

so...after a couple of months noodling about with the CMI IIx, I tried 
sampling some stuff last night.

First up was a kickdrum from a TR-909. Decay on the drum was to the longest 
and tune to almost the lowest, maximum click.

It sounds like shit ! No attack. sounds distorted. And with a fizzel on the 
decay part.

Sample rate was 30200
Filter low 3
Filter high 9

Then it struck me, I was going direct from the 909 to the CMI IIx line input 
via a 1/4" mono jack to XLR cable. Tip to Pin 2, Sleeve to ring and ground. 
The CMI being 600 ohms on both the line in and mic in......

Am I having impedanceproblems ?

 Today I brought some passive DI´s and transformerboxes from work....but it 
doesn´t seem to make it better.

Sampling the Snaredrum from the 909 sounds great though, but there´s not 
that much bass in the 909 Snare.

How are you guys connecting stuff to your CMI IIx inputs ? Are you using 
external pre´s ?

hallo WT.,

I gave up sampling at first ..the results where too poor.
Than someone one this list recomended a active DI box .
I tried again and there where some results...still quite poor.
somehow I always used the filter /line input.
only last week I tried the adc  direct input.,in combination with active di I sampled a dx7 piano and wow.....
for the first time I had good results......use the gain,max:*
command on page 6 to pimp the sound.
I was thinking....those guys who made the liberary used hi end compession enz. enz. enz. to get those results.
they prob. did but the IIx is capable of pretty acurate reproduction of sound without any precompression.
Realy...try to find the right di box and hook a synth up too it.,
i used a high output vol. on the synth and the results are great sounding cmi sounds.
the (cmi)dx7 piano actualy sounds warmer and has more depth than the original!

cheers,
David

Thanks !

Will raid the warehouse at work for some quality DI´s and preamps.....

Re: [Fairlight-CMI] Re: CMI IIX sampling

2010-02-15 by WT

I did connect to ADC just now and ran the 909 kick through my desk.

Had to use a phase-reverse adapter to get signal into the CMI as it is 
unbalanced and pin 3 "hot".

Made the sound slightly bigger ! Not much, but still larger.

However, it still has a large amount of noise on the decay of the kick. I 
hope that my CMI is not broken.

Can anyone confirm that this is normal for a CMI ?

I can email a soundclip if needed.

Re: CMI IIX sampling

Hi,

I think it's quite normal to have quite some noise in the samples.
I always assign control 1 to damping  c2 to filter and c3 on attack on page 7
in that way you have some analog realtime control.
with the filter you can usaly kill alot of the noise....than I use EQ on a mixingdesk.
I hope your cmi is o.k. 
with a soundclip others are able to judge..
did you try sampling other instruments or a mic ?

regards,
David

Re: [Fairlight-CMI] Re: CMI IIX sampling

2010-02-16 by WT

I´ll see if I can make some samples tonight.

Also, I´ll try with a microphone.

It seems that the noise is only heard when sampling bass-sounds with decay. 
Sampling a steady lowpitched waveform ( like a sawtooth ) from another synth 
doesn´t reveal the noise but that is understandable as the constant wave 
masks the noise. Even sampling a triangle or sine masks the noise.

Can you post a link to a recording of your sampled bass drum?  I know
that the 8-bit samples in my early versions of my replacement Alesis
HR-16 ROM had a pretty distinctive noise on long boomy decays -
particularly on 808 bass drum samples, there was a high-pitched sweep a
bit like a sync sweep on it.  This is an artifact caused by the lack of
dynamic range and relatively large steps in a linear 8-bit sample.  I
left it in, it sounded cool.

The CMI is 8 bit. You have to be very careful sampling into it.
Of course, it may be that yours has issues, but 8 bit sampling is pretty lo fi !

I´m pretty much convinced that it is working properly. I´ve done numerous 
testing with lots of sources and everything except an 808-style or 909 kick 
sounds fine.

I guess I´m spoiled with the superior sampling on the Waveterm B ;-)

Gordon,

thanx for the info below.

That is very much how it sounds. Like a sync-sweep.

I guess it is ok then. Doing the testing/calibration of the ADC is not 
something I´m capable of doing.

Is the the noise anything like "poink poink poink" noise on the bass
drums in this?
http://www.gjcp.net/~gordonjcp/mp3s/hr16.mp3

That's the HR16 samples I was talking about.

Yep !

not as smooth but definately that type of noise.

Ahh, that sounds like my Linn 9000 when I'm sampling kick drums.  Think that's why Bruce Forat came up with the Filter mod which also sounds great on Toms and Congas!  It's a neat little filter that really works wonders!
