Since the economy may not allow people to buy TOTL arrangers what would be a way for arranger manufacturers to possibly expand their market and keep their current customers happy without making a TOTL arranger?
Why not an arranger module.
Cheap ($1000 or less), full midi implementation, small, under 10 LBS and gives a preview of what is to come in their new TOTL arranger once the economy gets better.

This would be for persons who have keyboards already. And for those who have workstations that have a little of the arranger technology and the player wants to get in to arranger playing but not spend a lot of money.

I am thinking maybe Korg or Roland could take advantage of this (as we know Yamaha does not look at what could be economically feasible for the customer).

So if you have a G70 Motif xs or a T3, and like the Korg sounds and styles, or just want a little variety, if there were a Korg arranger module you could have that an not spend a lot of money (buying a PA 2x pro or PA 800).
The key to it is that it would have to be affordable. Because it would not be a necessary product but a desirable one. It would give a non Korg user a taste and may win them over when the next TOTL arranger comes out for Korg. Any manufacturer could do this Roland, Yamaha, Korg or Ketron. Although Ketron would not be able to do this right.
now.

In the case of Korg, Yamaha or Roland, they can have the module based on their current TOTL arrangers with a few of the sounds and features of their next TOTL arranger.

I just think the Ketron really is in a bad situation releasing a TOTL arranger in this economy. I don’t think that Korg, Yamaha or Roland would be putting out a TOTL until there are signs of the economy picking up.

What this does is that they do not have to rush to release a TOTL arranger they can continue to work and perfect on features before the release of the TOTL arranger.
