Are we twins?
I spent a long time struggling with keyboards and then settled on a WX7, later replaced by a WX5. When the Pico became available I bought one and now also own an alpha. For the WX's I use a VL1m, VL70 and a few soft synths. I also ventured into guitar (Dobro and Lap Steel)
So...
1) I'd echo everything NorthernUmber said above and add a few things
- the pico is quite a natural thing to shift to from a WX or EWI. I missed the lip sensor on the WX (I always played 'tight-lip' setting) an EWI player would find the shift even more natural. The Alpha/Tau is suitable plus adding greater scope but they are large instruments with base stations (I have and would recommend one of the longer cables). People have made 'gig-rigs' for them much like is done with wind instruments
-- being polyphonic is quite an advantage but not a good fit with many wind-optimized sounds (and, of course, the VLs are not poly). Wind soft synths are mostly amenable to tweaking.
- We just had a preview of a new fingering agent (yesterday) that will be available in the next experimental release (imminent) This will provide similar capability to a WX (or EWI or tin whistle, or anything you like - it is configureable) with some really interesting extensions for polyphony. I'm sure someone will post the link to the recording of the preview when it is available. I'm very excited about this.
There are a few reasons to struggle with a keyboard.
-One is a physical thing (my left hand is not up to it and isn't going to get there with practice, for example). The pico is not physically challenging at all (much like a WX/EWI). As to the others, even I am doing quite nicely (IMHO hehehe) with the Alpha. I would suggest that the Alpha/Tau adds a great deal of scope to a player who can master keyboard and brings otherwise challenging things into the reach of those of us who struggle with keyboards physically.
Another way one might find keyboards a challenge is one of mindset. Wind, instruments are primarily melodic, for example. Personally, I ended up down the melodic path by default. The eigenharps are an an amazing step forward on that path and provide a wonderful playing experience and expressive result. That said, they have also brought me full circle into a return to chordal thought and expression. The ability to use scales was part of this (both as an enabler and as something that causes one to explore music generally) but the keys were another, complementary, part as the chord shapes are more movable (like guitar) and an easier reach. I anticipate that the fingerer agent will add a whole new dimension to this as it matures.
Ok, well, I'll stop there having been too long already
