Hi Dave, When I build tracks for live-playing, I do 24-bit wave files and place them on a portable device. That way I just patch it into the PA system or the instrument that I'm playing on and go from there. I prefer to use uncompressed audio for my tracks. Several years ago, I was a concert artist for Panasonic Company; I used to be able to create custom styles on Technics organs and keyboards to use them in concert, etc. The instruments had a Composer feature that had tracks where you could build drum parts along with bass and other accompaniment parts that would follow chords as you played them in the left hand. They allocated enough memory to that feature so I could create decent length patterns and make them so you couldn't tell when it looped back to the beginning of the pattern. Since there are no more new Technics instruments being manufactured, I've had to retool things and move to building audio tracks that I can use on anything that has stereo line inputs. It certainly simplifies my operation to do it this way - and as long as I've got decent mixes, it sound's great. I don't have to worry about having to deal with hardware that's pretty much inaccessible. I'm an organist, and one of my gigs is that I play on a Roland console organ at my church. The instrument has Roland's version of a Composer feature, but the only way you can customize it is by creating midi files and converting them to the format that Roland uses for that feature. The only problem is that the software used to do that isn't available to consumers; so needless to say, creating custom accompaniment tracks is out the window. It's not all bad as I can take advantage of the power of Sonar and soft synths and do some decent tracks that work well in performances. The only disadvantage is that you're limited to the structure of the tracks. When I was able to create these custom accompaniment styles, I could use them for different songs that worked well with these style. I miss being able to do that very much as it allowed flexibility for live-playing. I recently purchased a new product that Freedom Scientific released a few months ago - the Plextalk Pocket, which is a Daisy reader. It also plays all sorts of audio file formats, including 16 and 24-bit wave files. All the data is stored on an SD card, and you can use up to a 32-GB card. It's completely accessible as it has a voice guidance feature that has its own volume control independent from the rest of the output signal. This should allow me to lower the guidance volume so that it isn't too noticeable during live performances. I have to pay attention to what's going on with it because it's configured to play all albums and tracks sequentially; so I just have to build my tracks with enough silence at the beginning and end of the track to give me time to stop the machine or scroll to whatever track I want and either stop it or let it play after the guidance has announced the title of the track. Prior to purchasing this unit, I was using an Edirol R09 HR recorder, but I never knew what track was up; consequently I ran into a situation on my last show that I did where I had trouble getting it to the track I wanted to use at a point in the performance. Needless to say it was embarrassing, hence my moving to the Plextalk Pocket. I believe that Olympus has some units that have voice guidance features as well, but I don't know how much accessibility you have. The Plextalk will tell you everything, so you can be assured that you're doing what you want to do with it. Since I'm primarily patching it into the organ, I have to tweak the mix on the tracks so that I get a good clean crisp sound as there's no way to adjust the EQ on the line inputs. It might be worth looking into if you're considering using an audio device for your tracks. Hope this helps. Cheers!

I would like to take that just a step further as wonder why some choose to have computers play drum machines and synths via midi rather than simply recording the parts and playing along to an mp3. I realize some do that as well but just wondering the advantage of using the midi verses recording parts and making an mp3 out of it to play with. Would think that having extra midi stuff would take up more room than an mp3 player if you aren't actually playing all of the parts. Thanks for any input as curious to hear opinions. Dave
