The Yamaha AN1x Synthesizer mailing list

Hi there,
Dave from Australia here, new to the an1x but loving fooling around 
with it. I have been using software synths in Logic Pro for the last 
couple of years and decided to take the plunge into a hardware synth. 
This is where I get stoopid. 
My problem is that I can't hear some of the voices (particularly bass 
voices) on the an1x. Also when i intitialise a voice using "template 
1,2,3,7 & 8 I can't hear the initial waveform to begin customising 
the sound. I can hear the waveform fine on 4,5 and 6 "template".Well 
I can hear it but only if I really crank the interface which also 
produces a lot of noise. 
I suspect this maybe where I am going wrong.. I have the an1x plugged 
into a single channel on my tascam fw1804 interface. I have a stereo 
out cable that goes from the synth to a single input to plug into my 
interface. Can someone advise if this is in fact stoopid and if so 
how to connect properly to my interface. Secondly could this explain 
the apparent lack of volume on some voices and initialised waveforms?
Despite my stoopidity I am loving the sounds of this thing. Special 
appreciation to the creator of the logic environments..now I just 
need to work out how to use them.
thanks,
Dave
