Hey there,

im a guitarist and I play in a band; and I was hoping to expand my 'tonal palette' (lol) by getting an electric keyboard.

I was originally looking at a synthesizer system for my guitar, but they are more money than I am willing to spend. Its just going to be something for me to play a few chords on, more as a textual/thing than as a lead (because I can't play anything else other than chords).

But, the world of keyboards is VERY confusing. Would someone be able to tell me WHAT I am looking for? i.e the type of product I should search around for?

I
-don't need a complete range of octaves
-need something that I can plug into a different speaker/PA (i.e not an onboard speaker ONLY)
-desire I good palette of sounds, particularly ambient style things and strings
- WOULD LIKE ability to customise some sounds (I realise this bit is probably a more expensive feature, requiring PC use and stuff?)
-would like to perform without using a computer.

Any tips on what sort of thing im looking for would be appreciated?
ie, do i need some midi system or a stand alone keyboard...

thank you all
