I tried it with the DC drive alpha, it works quite well, but like 10% flux compared to 3 % of the 0 crossings method. I wish you could play with my turntable, you might be able to refine it.
Thanks for this 8D
I am using your direction method yet.
ps. perhaps the delay you found with mine was the time it takes to cycle once, also you can stop low level input causing the position to move with the noise gate

Haven't seen any info on this yet - it's maybe a stupid question but what exactly do I have to do with .osm file? What I actually want is to use hard drive with Traktor Pro as midi device, is that even possible?

Pointer, First welcome to SM land :)

Do you have Synthmaker Installed? the .osm file is a workfile for Synthmaker which is a vst plugin development enviroment.Synthmaker can also export standalone applications.

You could try downloading Synthmaker free from here and build yourself a midi plugin or application for use with Traktor

SM FREE >> http://www.synthmaker.co.uk/forum/viewforum.php?f=23

I am sure there will be ppl who will guide you on your way :)

Hope this helps

This is an extremely dumb question, but I honestly do not know the answer.

For the stereo audio cable, I'm looking at an RCA-3.5mm one right? Plugging the 3.5mm into the line-in on my board and then cutting it somewhere down the cable to connect the R, L, and ground to the motor contacts? Will the ground be in the R/L's insulation?

I guess what I'm trying to ask is...

Thanks, I've tried installing it but I'm getting DirectSound could not be started error (it says that some other app is running ASIO, that's not true). Damn.

NEVER PUT A HARD DRIVE IN YOUR MOUTH OR TRY TO SWALLOW IT!

I must have to much time on my hands. I started to worry about all my Synthmaker friends scratching their Dj sets out on potentially hazardous hard drive internals so I looked it up. Hardrive toxicity? http://www.techspot.com/vb/topic62574.html some definite lol moments in this thread. :D

If you feel like taking this post seriously (Don't) there is this pdf on toxic stuff in computers. http://www.greenpeace.org/raw/content/international/press/reports/laptopreport2.pdf
A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.

Hi,

Sorry to ask such a basic question. I have got all the hardware functioning but not the software side. I am using the free synth maker software and its not picking up my hardrive signal even though my computer picks it up through the input. I would really appreciate it if you could help me with the software. Thanks so much

Here is my software, please don't share it without asking, thanks-
tablist_0_32_sm2.osm
(196.65 KiB) Downloaded 269 times

hmm
I don't know if it will work though.
Try the levels and gate first perhaps.
Cheers
Get back here if you like and we'll try and sort it.

Hmm,
If you have selected the correct ASIO port on the 'ASIO in' primitive, and enabled your soundcard(the name will be highlighted in blue) you should get the signal.
You can test to see if you are getting a level with 'Level Meter' module.

...here is a modified version i made. converts the audio signal from the HDD to a midi CC message.
it´s optimized for my modded HDD but with the "SENS" knob you can adjust the sensitivity to your needs.

Hello

I've got a stupid Question. I have build now my own HDD Turntable, and by the way i have tested it with an Scope, and got the same Sinus wave what is recomended. My Question is now how can i Use this Turntable now in Fruity Loops? I have tested over 5 .osm files for Synthmaker, but nothing moves or is disturbing the sound when i move the HDD. I have tried it in my Onboard soundcard and the line in with a cinch and conntected it with the 4 connectors on the HDD motor, and for a second time i used the 2 channels from my USB Soundcard (EMU 0404)... Where is my problem? is it a configuration problem in the sound settings, or do i have to edit somthing in SynthMaker?

Sorry for my Bad Englsih ^^

My Setup:

1. Connecting the HDD with my Soundcard (Realtek Sound on Board)+(USB EMU 0404)
2. Open FruityLoops
3. Open the Synthmaker
4. Open one of the .osm files
5. Start playing (and i tried to open a mp3 in the "Sample Picker"
6. Moving the disk (nothing happened)

Sorry but iam a noob in SynthMaker and FruityLoops, but it will be nice if anyone can help me out... Thx
