hi Ized,
welcome to the keyboardist's world..!
u may want to familarise yrself with the terms b4 u actually ask about what u want first...
my impression of the hiearachy of keyboards is this....many people have been asking me how to buy "low budget keyboard" but many do not actually know how what they actually want and even what are the proper keyboard terms to use...
tis is how i try my best to put it simply....this has been done so many time b4 by the xperieced old birds in here but i figured i can give it a noob shot:
1. keyboard: plain simple keyboard with the usual different patches/or "sounds"..many guitarists like to call them 'effects" but we keyboardistist call them patches/voices. a low budget keyboard usually has no or little effects( cept for the basic reverb/chrous etc). some comes with basic EQ function, most do not. current trend is about $250 And above usually. usually has no or ittle real time controls( knobs, pitch bend wheel etc)
2.synthesizer: keyboard that is programmable,( tink tweakable, layable, can combine patches etc) , no "recording"function (we keyboardists usually call it a sequencer ) usually comes with much more comprehensive and programmable effects set, and real time controls like knobs and wheels.(i.e guitariss: tink delay, phaser.flanger, and EQ, and the tone and volume knobs and wah wah ) current trend is about $700 and above usually...
3.workstation: synthesizer with sequencer and perhaps sampling function. if u can get a first hand at $1000, its reali okie. Yamaha heated up the competition with MM6, about $900+
shall not go on ..but when u mention loopin,you could be talking about the workstation range...unless u can get some keyboard with simple recording functions....some cheqp Yamaha PSR can record a track or two and has SM slots..they can record tracks but i'm not sure about looping.....
