I have a step by step guide on my web site which should help you set up a multi timbral synth such as TTS to play as many as 16 different instruments per instance. 

Using just 4 instances you could feasibly have  a 64 piece orchestral composition. 

This is the direct link http://www.herbhartley.co...edited_slimmer_005.htm it's the 3rd paragraph down...Advanced TTS set up

  A number of other people through the years have had problems understanding TTS and how to make it play several instruments at one time..... this page has help them. 


I hope this helps you.

Hi Deensay,
Glad we could help and that you are happy!  I am new to this forum too and I have found the people here are exceedingly helpful and supportive - quite rare these days!  Like you I was an amateur 'expert' * with midi back in my youth and I am thoroughly enjoying re-living it, but now I have a bit more money to indulge my hobby!!

 MC6 is a great piece of software and the interface is very similar to the top of the line X2 Producer, so if the bug does bite the upgrade path should be relatively painless.  I started out with MC6 on my laptop and a simple keyboard.  I have now upgraded to X2 Producer and have 'upgraded' a lot of hardware and I am in the process of building a dedicated PC just for my amateur recordings - once you start.....

– Sample Tank seems to have the best piano sound I could find so far. Sample Tank works fine, but I get some warning about administrator privileges, and I cannot get rid of it.
– Independance has incredible acoustic guitar sounds.
– MC6 is perfect for me, just as you say, LordElpus. I cannot see the difference with Sonar X1 LE, apart from TTS-1 of course, which is ideal for General Midi.
It turns out that the best setting to make latency as slow as possible is with "WDM/KS" as driver mode. Other choices are "WASAPI, ASIO, and MME (32 Bit)". MME seemed to be the default mode, but I couldn't set latency lower than 60ms, which was actually too much. I have no idea what all these modes are, but WDM/KS allows me to set latency to 1ms. I realized that Sample Tank crashed (and made MC crash as well) when latency is set to 1ms, so I had to increase the value.
ASIO seems to be the most popular solution to latency problems, but I couldn't get it work with my Quad Capture sound card.

Good to see you making headway.
The administrator privileges thing is coming from W7.
In Windows Explorer, go to the Sample Tank folder and right click on the executable file(SampleTank2.5.exe)
Select Run as Administrator.
There's nothing wrong with WDM. If the drivers are well written, they can be as good or better than ASIO.
One may work better than the other, depending on system configuration.
Since WDM seems to be working well on yours, run with it.
Super low latency is good for recording audio, particularly vocal tracks, but as you've noticed, can be problematic with soft synths. Synths need a little headroom. 5-9ms is a good range. You will not hear or feel a difference, and it gives the CPU the time it needs to do its work.
Carry on, and have fun.
