I have noticed with a lot of digital keys,they sound great thru studio monitors and headphones.But,in live venues at low volume they sound "weak". For example, i was sitting about 20 rows back,listening to our bass player,thru a hartke amp with a 15" speaker,again low volume.I could hear and feel what he was doing.Sometimes,having to cover bass parts,i can get a good sound,but just not the punch or sustain.Same with some organ,piano,rhodes sounds,a big lack of projection,sometimes even couple feet away from the monitors. Any ideas?
