The audio jacks are mono, so the ring of the second earphone is likely grounded and you won’t hear that second output unless you use some sort of an adapter or a mixer.
For the sequencer, doublecheck the manual - you’ll have to navigate to the clock page and adjust mod from step to seq. Then when you start the Let’s Jam mode, it should start playing the sequence.
The factory patches are about halfway down on the Firmware page. Keep in mind these were mostly designed around the SMR4 filter board, so if you’re using anything different (especially one of the dual SVF or the digital filter boards), they may not sound very useful.
It’s less complicated than MIDI OX and it’s more reliable, on some synths. There’s a slider in the settings to set the transfer speed, which is the cause of a lot of problems sending patches to synths - try it on the default 1:1 speed, then try it a bit slower if that doesn’t work:
@Slugz Also, try the patches linked to on this page, provided by pichenettes:
That’s a zipped archive of patches/presets for the Shruthi and the Ambika, stored as individual patches, in a few different sub folders. You may have more luck uploading patches one at a time, rather than a big chunk of multiple patches.
If you have to use MIDI OX, experiment with different buffer sizes. I’m not sure if there’s a transfer speed setting because I mostly just use it as a MIDI monitor, and use Bome’s Send SX for sending patches, or dumping them.
