Danlsk Posted July 30, 2021 Share Posted July 30, 2021 While many of Casio portable digital piano has audio input port, the higher end series Cleviano series such as AP270 and AP470 models are missing such audio input port to amplify acompaniment audio sound via its speaker. PX-S1000 and PX-S3000 has bluetooth audio support and audio aux input. I am suggesting that AP470 that has USB flash drive port to have USB compliant sound card driver support in the system so that a USB sound card adapter can be plugged in to support audio input. This can be done via firmware update if the system hardware can support it. Quote Link to comment Share on other sites More sharing options...
Mike Martin Posted July 30, 2021 Share Posted July 30, 2021 No this can not be done via a firmware update, this would require a significant hardware change. 1 Quote Link to comment Share on other sites More sharing options...
