Sequencer Ideas

[Nextherex]

Try harpsichord, and high sine for recorder or flute. You may also want drums. Perhaps harp to substitute a lute. I would also try smooth synth to fill in the vocal frequency range

Depending on the wealth of your band, you may instead want to do a more orchestral style with trombone and violin and pizzicato, and stuff like that.

If you are going for a more modern video game take on medieval don't be afraid to add jazz guitar and piano and really anything along with some of these listed instruments

Thanks!
