Not sure if this group is still alive but since there's so little Q Chord information out there, I figured I should post my review.

-----------------------------------------------------------------------------

Personal Bias
I was looking for an upgrade or replacement to my 21-chord autoharp that would be suitable for use in a church setting. I have about 3 years piano and trumpet experience, 5 years autoharp, and wrote this review after 3 weeks with the Q Chord.

Differences moving from Autoharp to Q Chord
- Q Chord costs somewhat less than a 21-chord autoharp
- Same top row layout but with more buttons on both sides
- Bottom two rows line up with the top row instead of using autoharp grouped chords
- Minor and 7th rows are swapped
- Needs batteries or power adapter
- Q Chord voices tend to have a higher "bright" electronic sound
- For amp usage, it would need an electric amp rather than an acoustic

Advantages over autoharp
- Can transpose up 6 or down 5 half steps
- 12 buttons for an immediate 36 chords vs 21 on autoharp. Can also hit button combinations for augmented and diminished chords
- No strings to tune
- Standard case is much smaller and lighter for storage and transport
- about 100 different instrument voices available
- Automatic accompaniment options with individual settings for chording and rhythm
- Can adjust sustain, reverb, and vibrato
- Includes a piano overlay card. Good to help figure out a melody but has no auto chording in piano mode

Negatives / Suggestions for a Future Release
- Collects fingerprints easily -- wipe cloth is included
- The lightweight material gives the Q Chord a cheap plastic feel
- Cannot save settings. Suggestion to add memory features to store song settings or save to cartridge
- 90 day warranty. Not sure how repairable if an electronic component fails
- Changing to the other voices is not intuitive. Could make a programming overlay card to access more features
- Reportedly poor midi support. (I have not tried to use midi)

Feedback
- Can shut off drums with EZ Play or turn down rhythm volume and turn on chord hold
- Sounds much better through an electronic amp
- Helpful to have headphones for quiet practicing (has a 3.5 mm plug so I got a 2.5 mm adapter for my headphones)
- Piano players tend to have trouble adapting to the autoharp-style layout (F,C,G,D,A,E,B rather than C,D,E,F,G,A,B)

Conclusions
The Q Chord is pitched at the absolute beginner (or for therapeutic purposes) with the plug & play song cards, but beginners might not want to spend $300-$400 on a "toy," and professionals tend to be put off by the negatives.

However, I highly recommend the Q Chord for amateur musicians who have a little music theory, and want an instrument that will grow with them and can be learned at a casual pace. The Q Chord is a much more versatile instrument than the autoharp, and I have found it quite liberating to be able to play music without the autoharp limitations. The Q Chord is probably one of the easiest "pick up & play" instruments that can deliver impressive results with minimal learning requirements.


Post your QChord videos, songs, and observations here. There are other sites that include the Omnichord, so I would like this community to focus specifically on the QChord. I won't be legalistic about it, but it would be nice if we could focus on the capabilities and challenges of the QChord specifically. It would also be nice if we could avoid making this primarily a site to post QChords for sale. There are obviously other, better places to do that. I don't want to have that noise here.
