Hi Tony,
Whether anyone else can do what I have done for several Korg PA arrangers is not for me to answer,but personally I would say yes if they have some good insight knowledge and hundreds of hours of time at their disposal. Do not forget that as regards my resources for the Micro Arranger I owned the PA50 ( identical as you know) for more than five years, hence my programming on it is very comprehensive and you cannot expect the manufacturer to spend that amount of time on making Performances, sounds etc. Furthermore it should be noticed that there is no accounting for tastes. As mine are pretty much MOR , most of those who ordered my resources have been quite happy with them.
As regards there being a glut of Yamaha software on the market FOC I can only remark that the Korg market is slightly a different one. For starters the Yamaha players lean very heavily on songstyles etc. Soundwise of course the Korg and Yammies have always been different hence my personal mantra "if you can afford it get both brands, at whatever price level.".
I know for a fact that very very few people (if any at all) have delved into sound and performance programming for Korg the way I have, as shown by the testimonies on my webpages of those who are using them. It must be said that in general the Yamahas require less tweaking from the start and most players are quite happy with the factory stuff and the masses of styles they can download FOC or at whatever price.
Talking of which I merely ask for a 25 euro donation which enables me to maintain my hobby the way others do some gigs a month. It does not make me a rich man but has enabled me to move up from the PA500 to the PA800 over the last 18 months. I am sure none will begrudge me this improvement. Furthermore it should be emphasized that I commit myself to refunding this donation should anyone not be fully satisfied. All this can be found on my webpages, for the Micro Arranger see pages 7,8,9.
You being British should know as no one else that "the proof of the pudding is in the eating ". If you do not want to buy a Micro that's quite okay with me, but why don't you try and get one on trial for one or two days. I will be happy to send you my best resources plus guidelines, even how to play it (or part of it) via your T4 keybed, and then you can finally have a well informed opinion of your own. My bet is that you will want to hang on to it......................
kind regards,
John Smies
