Ranked by what users actually praise
A cheap way into classic Roland/Boss SP sound. Multiple owners picked up an SP-505 for $100-$125 and call it a bargain next to the pricier SP-303 or SP-404, saying it 'can do it all and is superior in several ways.' The vinyl simulation and lo-fi grade sampling give it a vintage character that drew buyers away from chasing other lo-fi gear like Ensoniq samplers, and many say the low price makes it a safe, even profitable, purchase.
Deep FX and external resampling set it apart. Commenters repeatedly praise the Filter+Drive and Phaser effects as genuinely good, and highlight the ability to resample an external source while simultaneously recording a drum pattern as a killer, overlooked feature missing from the 404 and 404sx. Combined with a four-track sequencer, song mode, and pattern chaining, several call it more of a full beat-making workstation than rival SP models.
Slow processing and quirky workflow test patience. The most common complaint is speed: chopping samples, saving/loading via SmartMedia, and scrolling with the jog wheel are described as painfully slow, like 'an old man waking up.' Users also struggle with moving chop-bank samples into user banks for sequencing, BPM sync issues, cryptic errors like 'Protected' or preset-update failures, and aging build quality such as failing FX knobs and stiff buttons.
